What is Nano Silica?

/ / no Comments

What is Nano Silica? Silicon Dioxide Nanoparticles also known by silica nanoparticles and nano-silica appear in the form white powder.
According to the structure of nanometer silica particles, they can be divided into P and S types. P-type silica particles are distinguished by their large number of nanopores. Their porosity is 0.61 mL/g and have higher UV reflectivity than S type particles. They also have a very small surface area.
Nano silica features a light volume, fluffy bulk density, less than 0.15-0.2g/cm3, an area specific of more than 500m2/g, high chemical activity, and a large surface area.
The surface of nano silica contains an OH bond. This makes it a silicate group type of acid oxide. It has hydrophilic water absorption rates that exceed 5 times their own.
Silica nanoparticles have many uses. They are used as additives in rubber, plastic manufacturing, reinforced fillers for concrete and other building materials and as a stable, nontoxic platform for biomedical purposes such as drug delivery or therapeutic diagnostics.

What is Silica?
Silicon (or simply silicon) is one of the many chemical elements found in the earth’s crust. Its oxide forms include silicate (SiO4), and silicon dioxide [silica, SiO2].
It is common to use silicon in industry. The oxide form is often used in biomedical and industrial applications. SiNPs are rare because of their unique properties. These include ease of synthesis and surface modification, strong mechanical property, and relatively inert chemical structure. They have been used in biological materials for many decades.
Silica can be found in two forms, crystalline and amorphous. Although they share the same molecular structure, these two basic forms of silica have very different structural arrangements. Crystalline silica features a regular lattice arrangement while amorphous is more irregular. There are many forms of crystalline silica. Alpha-quartz is the most well-known, and can be transformed by heating to b-quartz or squamous silica. Porosils are porous crystalline silicon, which is also known as porous silica. All porosils come from synthetic materials.
Because of their rare properties (high surface area, high volume, adjustable pores, good chemical and thermal stability, and large pore size), silica and mesoporous silicone are great candidates for controlled drug releases. There are three main types of amorphous silicon: natural, byproducts, and synthetic. Because of its biocompatibility with other elements and stability, amorphous silica has been considered a very promising candidate for molecular image and gene carrier. It is used in dietary supplement, dental fillers, catheters, implant, and implant therapy.

What uses is nanosilica?
Nano silica can be used to modify cement concrete's dispersion, plasticity and temperature. It gives it impermeability, enhanced permeability, frost resistance and reduces hydration heat.
It can be used as a vitrification agent, strengthening agent, adhesive, and glue of ceramics, enamels and glazes. It is also used as a high thermal binder in engineering-grade and refractories.
Use nanocomposite materials modifier as an inorganic adhesive at high temperature. Also used as an additive to inorganic composite materials for strengthening, molding and filling of rubber/polymer material. Additionally, it can be used in a variety of resin engineering material; High-quality FRP packing that is corrosion-resistant.
It is used to cement seal oil wells and as reinforcement material for under-ground engineering.
Use for special purposes, including lamp paint, lubricating oil, thickener or steel dehydrogenate and inner wall paint sensitive material. For solar cells and power cell energy storage.

Is nano-silica toxic?
Exposed to silica, particularly crystalline, has been extensively researched.
Studies have shown that workers are exposed to crystalline silicona at work, which can lead to silicosis. This is a fibrotic lung condition that can also be caused by other diseases such as lung cancer, emphysema, or tuberculosis.
Amorphous silica used to be considered less toxic than crystalline. Recent research has shown that SNPs that are amorphous have toxicity levels similar to crystalline particles. SiNPs' physicochemical and crystallinity also produce different levels of toxicity in vitro as well as in vivo. Consider safety and possible adverse effects, especially those that may affect the immune system.

Lithium Battery Anode

Nano Silicon Anode Material Si Powder CAS 7440-21-3

/ / no Comments

About Nano Silicon Anode Material Si Powder:
Silicon is the most promising electrode material for the next generation of lithium-ion batteries, with a specific capacity (3600 mAh/g) about 10 times higher than graphite (372 mAh/g). However, its use is severely limited due to the significant expansion of the material in the loaded (lithified) state (over 300%) and the instability of the solid electrolyte interface layer (SEI). The poor mechanical stability and chemical passivation properties of the silicon electrode make the cyclability of the silicon electrode far from meeting the requirements of the battery system and have inspired a large number of studies and proposals to circumvent these limitations.

During lithium insertion, the volume of silicon changes so much (~400%) that the silicon breaks and falls off the collector, resulting in a prototype lithium-silicon battery losing most of its capacity in less than 10 charge-discharge cycles. The key to the success of high-capacity lithium-ion batteries is to solve the problem of the capacity and stability of lithium-ion silicon.

Silicon anode materials show great potential for improving the efficiency and energy storage capacity of lithium-ion batteries. Until recently, their main drawback was surface oxidation passivation, a process that increases impedance and reduces the circularity of the anode. Our high purity silicon anode materials achieve high specific capacity without significantly affecting cycle life. Orachemicals is a trusted global Nano Silicon Anode Material Si Powder supplier.

Silicon carbide ceramic

/ / no Comments

Silicon carbide is made from silicon and carbon. It's a very tough crystalline compound. SiC is the chemical name for Silicon Carbide. Since late 19th-century, Silicon Carbide has been a key material in the production of sandpapers and other cutting tools. Silicon carbide has been utilized in recent years as a refractory coating and heating element of industrial furnaces. It is also used to protect parts of rocket engines and pumps, and for semiconductor substrates of light emitting diodes.

Silicon carbide semiconductor
The third generation of semiconductor materials made from silicon carbide are after the second generation elemental semiconductors (Si and Ge) as well as the second generation compound semiconductors. The characteristics of silicon carbide as a semiconductor material have a large band gap. They are strong in radiation resistance and chemical stability. Due to its high temperature resistance and resistance to pressure as well high frequency, it has been used extensively in the power electronics field.

SiC can be found in many polycrystalline structures called polymorphisms. At this time, the preferred choice for actual power device manufacturing is 4H-SiC. There are single crystal 4H–SiC wafers available with diameters from 3 to 6 inches.

Silicon carbide vs. Si
SiC offers a ten-fold increase in dielectric breakdown strength, band gap, and thermal conductivity compared to Si. SiC can be used at higher temperatures and has a higher resistance to voltage.

Preparation and use of single SiC SiC-rich crystal
Silicon carbide substrates can be prepared using PVT, solution or HTCVD. The world's most popular method for preparing silicon carbide single crystals is the PVT technique. SiC single crystal growth involves three steps: Acheson, Lely and modified Lely.

SiC crystals can also be grown using sublimation methods, such as the Lely method. You place the SiC powder between a graphite crucible, porous graphite tube, and it is sublimated. It then gets grown in an inert gas (argon), at 2500 degrees Fahrenheit. It is possible to form SiC crystals in flakes.

But, as the Lely method relies on spontaneous nucleation, it's difficult to manage the crystal shape of SiC crystals grown by this method. Also, crystal sizes are very small. There was an improvement to the Lely method: The physical gas transport method (or PVT). It has the advantage that SiC seed crystals are used to control the crystal structure of the grown crystal. This overcomes some of the weaknesses of Lay method for spontaneous nucleation. The single crystal SiC crystal can then be obtained and can be grown.

Silicon carbide ceramic
The process of reactive bonding which is used to make silicon carbide ceramics was created by Edward G. Acheson (1891). The Acheson process is where pure silica and coke react with an electric furnace. It can be heated to temperatures of between 2200 and 2480 degrees Celsius (4000 deg-4500 F). SiC ceramics exhibit excellent high-temperature bearing strength and dimension stability. Their high thermal conductivity makes them resistant to heat shock. High thermal conductivity is used to prevent extreme temperature variations between layers. This can be a source of thermal expansion stress. SiC makes a great kiln-furniture to help other ceramics through the firing process.

Price is affected by many things, such as the demand and supply in the market and industry trends. Economic activity. Unexpected events.

Silicon Nitride structures and properties

/ / no Comments

Silicon Nitride provides two crystal structures: b–Si3N4 and . Each of these three-dimensional networks are composed of common verices of [SN4] and belonged to the hexagonal system. Their differences lie in the order and number of [SiN4] trihedral layers. The overlap of hexagonal rings layers in the direction of [SiN4] tetrahedrons is what creates the b-phase. In contrast, the a-phase is created by layers of tangible transform and non-hexagonal layer. It can dissolve oxygen from a variety of crystal structures. Because the internal strain for a phase is stronger than that of the b, the free energy of a Phase is also higher than that in the b. According to thermodynamics the stability of the b-phase is greater at higher temperatures. Because of its low symmetry, the aphase is very easy to form. At 1500°C, the aphase undergoes reconstruction and becomes the b phase. It is impossible to reverse this transformation, so it is important to have certain process conditions. When the temperature drops below 1350, a-Si3N4 will form. However, bSi3N4 can easily be made at higher temperatures than 1500.

Silicon Nitride properties
Si3N4 describes the molecular structure of silicon nitride. Si is responsible for 60.06% while dint N makes up for 39.94%. Si3N4 is strong because of the covalent bonds between N and Si (of which only 30% are ion bonds), and has high hardness (9 More hardness 9), high melting points and stable structures.
Si-N crystals of silicon nitride are mainly composed of covalent bonds. Because the bonding strength and bonding strength are high, they have a large elastic module (4.7 x105kg/cm2). Although the coefficient of thermal extension is very low, it is high in thermal conductivity. It is therefore difficult to generate thermal stress. The material has excellent thermal shock resistance as well as good thermal shock resistant. The material has high strength and low temperature deformation. At 1200 x 1000h the silicon nitride calcimic ceramic has a 2.5g/cm3 dense and is deformed at high temperatures of 0.5%. This also applies to 23 x 7.kg/cm2 (load). It is resistant to oxidation, and provides good insulation.

Silicon nitride does not melt and is sublimated and dissolves under atmosphere pressure at 1900. The specific heat of silicon nitride is 7111.8J/ kg. A phase's microhardness is 1016GPa while the phase in b is 24.532.65GPa. The strong covalent bonds compound means that no liquid phase is formed below the temperature at which it was decomposed (around 1900). Silicon nitride materials are therefore able to be sintered by using oxide additives. Oxide materials which promote sintering include Al2O3, Y2O3, and so on. The high amount of addition can even reach 20%. It is a reaction process where the SiO2 oxide layer on silicon particles reacts with the additional oxide to create liquid phase. The grain boundary permeates the liquid phase to allow for good diffusion to enable material migration.

Chemical stability of Silicon Nitride
Si3N4 can be used as a thermodynamically stable material. Silicon nitride ceramics may be used as high as 1400 degrees in an oxygen atmosphere, and up to 1850 degrees in a neutral or reducing environment. Si3N4's oxidation reaction occurs at temperatures above 800C.
Si3N4+3O2=3SiO2+N2.

A dense layer of silica protection was slowly formed over the surface. This prevented Si3N4 from further oxidation. At temperatures above 1600, the weight gain wasn't obvious. In humid environments, Si3N4 is much more difficult to oxidize. Surface oxidization begins at 200 (which is twice the speed of dry air). Si3N4 in water vapour has an oxidation activation energetic that is lower than the one in oxygen or air. This is because Si3N4 can be reacted with water vapor through SiO2 films.
Si3N4+6H2O=3SiO2+NH3.

Silicon nitride does not react to corrosion. Cu solution cannot be eroded in an inert or vacuum environment. However, Mg can react with Si3N4 weakly; Si3N4 solution can wet Si3N4 causing it to erode slightly. Si3N4 transition element solution can strongly wet Si3N4 forming silicide with Si which can quickly dissolve silicon nitride while also escaping N2. While Si3N4 can withstand alloy solutions like brass, aluminum, and nickel silver it does not corrode well to stainless steel or Ni-Cr.

Other than molten NaOH, HF and Si3N4, silicon nitride exhibits good resistance to chemical corrosion. Si3N4 is able to interact with most alkali, salt, and molten acids that can decompose the silicon nitride.

Silicon Nitride for Refractories.
High temperature ceramics made of silicon nitride are known for their promise as promising materials. They have excellent properties at high temperatures, including high heat strength, wear resistance, corrosion resistance and good resistance to corrosion. The strong covalent bond at high temperatures and low diffusion coefficient make Si3N4 ceramics difficult to manufacture. The limitations of equipment and production costs are not easily accepted by the metallurgical sector. This means that research into refractories is often late in its development and does not go deep. While there are many theories based on ceramics, not much new research is available. The bonding phase of refractories was the usual form for silicon nitride in the past. Fine powder was combined with aggregates like corundum and silicon carbide by nitriding metal Si. This allowed for the combination of refractory materials. Part of the fine powder and silicon carbide aggregate ceramic shed plate are made from fine powder. The nitriding of Si metal to create silicon nitride forms silicon nitride. Combining silicon carbide with silicon nitride is what results in silicon nitride-bonded silicon carbide material. This material can be used for blast furnace bodies and other applications. The material's performance has been significantly improved. It is much more stable than clay-bonded silicon caride shed plate. The high temperature performance solves bulging problems caused by the oxidation.

: History and Development American Acheson fused Diamond experiment discovered silicon carbide. He mistakenly thought he had found a diamond combination in his laboratory. Acheson then studied 1893 industrial melting silicon carbide methods. We often refer to Acheson furnace as being in use today. First detected in meteorites was silicon carbide in 1905. The first silicon carbide crystalled was made in 1907. Boston was the site of the inaugural World Silicon Carbide Conference, which took place in 1958 for scientific exchange. The research findings of CREE led to the establishment of a production line for silicon carbide. Suppliers began selling silicon carbide in 1987. Application of silicon carbide

Silicon carbide can be used as an abrasive. It can be used such as grinding wheels, whetstones, grinding heads, sand tiles; as a metallurgical deoxidizer, high temperature resist material, and high purity single crystal.

Application and Market Analysis of Silicon Nitride Ceramics

/ / no Comments

Silicon Nitride Powder Property

Silicon nitride (Si3N4) A covalent bonding compound made of silicon and nitrate. It was first discovered in 1857. In 1955, it was made into a mass-produced ceramic material. Silicon nitride clays offer many benefits that other materials, including metals and polymers, like high resistance to heat (bending strength of 350MPa at 1200), resistance to acid and alkali corrosion, self-lubrication, etc. These ceramics can be found in many areas, including aerospace and national defense.

Preparation The use of Silicon Nitride Ceramics

To prepare silicon-nitride ceramic material, it is necessary to first obtain silicon powder. Next, molding, sintering, and other processes are used to produce the required silicon nitride. There are three main ways to prepare the silicon nitride powder: liquid phase reaction, powder nitriding and self-propagating high temperatures synthesis.
There are three primary forming methods for silicon nitride ceramics: cold isostatic, dry, and tape pressing. Meanwhile, the major sintering processes include hot pressing sintering (hot isostatic pressing), spark plasma sintering, and air pressure sintering.

Silicon Nitride Ceramics Applications in Mechanical Industry

Silicon nitride Ceramics are principally used in the mechanical sector as pipes, valves and tools.

When in use, silicon nitride bearing balls can reach speeds of 600000 revolutions/minute. They are mainly used for precision machine tool spindles, high-speed motorized spindle bearings, aircraft engines, automobile engine bearings, and other equipment bearings.

The advantages of silicon nitride ceramic bearings ball over steel ball are: high density, low temperature resistance, selflubrication and corrosion resistance. Ceramic balls are high-speed rotating bodies that produce centrifugal pressure. The low density silicon nitride lowers the stress placed on the outer rotating ring.

Dense Si3N4 ceramics have high fracture toughness, high modus, self-lubricity and self-lubricity. This allows them to withstand a wide range of wear conditions, such as extreme temperature differences and ultra high vacuum. These bearings will likely be used widely in many industries.

Silicon Nitride Market Analysis

American, European and Japanese companies still control the high-end production of silicon nitride ceramics. Well-known foreign firms still control the international market share as well as leading forces in development direction. Most representative are Toshibx Seridan (Japan Kyocera), Toshibx Seridan (CoorsTek) and British Sailon.

What is silicon nitride used for?

/ / no Comments

Silicon Nitride was discovered during the late 19th century. However, it's difficult to manufacture because of its covalent bonds. A type of engineering ceramic with excellent chemical and thermal stability, silicon nitride is high in strength and hardness. The polycrystalline form of Silicon Nitride is a type of composite made of single crystals (silicon nitride) that are embedded in either amorphous, partially crystalline or crystalline glass phases. These properties are not dependent only on the intrinsic properties silicon nitride single-crystals. They also depend on the size, morphology, and volume fraction of the glass phase at silicon nitride's grain borders. Si3N4 can be used for both traditional and more innovative applications. Si3N4 has many advantages, including its light weight, high wear resistance, excellent bending strength and durability. This makes Si3N4 an attractive alternative to conventional materials like stainless steel and tungsten carbide.
Automobile industry.
The automotive sector is one of the most important uses of sintered silicone nitride. For example, there are electric plugs in diesel engines that provide faster start-up, precombustion chambers that produce less emissions, lower start-up, and more noise and turbochargers that reduce engine lag. For spark ignition engines silicon nitride helps reduce wear rocker pads and turbocharger turbines reduce engine lag. Exhaust control valves increase acceleration.

Bearing.
An all-ceramic silicon nitride bearing does not just have ceramic components, it also has a ceramic hybrid bearing. For example, the ceramic ball and steel seat rings are made of silicone nitride. The silicon nitride clays offer superior shock resistance to other ceramics. Ball bearings constructed from silicon nitride ceramics have high-performance bearings. NASA's main engine uses silicon-nitride bearings. Because silicon nitride balls bearings are more durable than metal, they have less contact with the tracks. This is a better alternative to traditional metal bearings. They can lower friction by as much as 80%, improve service life by up 3-10 times, speed up by 80%, decrease weight by 60% and run in inadequate lubrication. Silicium nitride is 79% lighter that tungsten caride balls. Silicon nitride bearings are used in automotive bearings of high quality, as well as industrial bearings. They can also be used for racing, cycling, skateboarding, skateboarding, and roller skating. These bearings can be used in areas where metals cannot be used due to corrosion.

High-temperature material.
Since long, silicon nitride is used for high temperatures. Particularly, silicon nitride has been found to be one of the few integral ceramic material that is capable of withstanding severe thermal shocks as well as thermal gradients created by hydrogen / oxygen rocket engines. NASA scientists employed advanced rapid prototyping technology in order to produce one-inch combustion chamber / nozzle (thruster), assemblies. Five cycles were run on the thruster with hydrogen/oxygen propellant. The last cycle was a five-minute one at 1320°C.

Health profession.
There are many orthopedic uses for silicon nitride. It can be substituted for PEEK and titanium in spinal fusion devices. The materials' strength, durability, reliability, and resistance are significantly higher than those of PEEK (polyether ketone) and titanium. Some components of the material are antibacterial, antifungal and antiviral.

Tools for metal cutting and welding.
It is an ideal material for the cutting of tools because of its hardness, thermal stability, wear resistance and durability. It is particularly recommended to high-speed cast iron machining. Sintered silicon Nitride can be used to machine cast iron, nickel-based alloys, and hard steel at 25 times the speed of conventional materials, such as tungsten caride. Manufacturing output can be greatly affected by the quality of cutting tools. The face milling process of gray cast steel with silicon nitride can reduce the cost per part by up to 50%, allows for a faster cutting speed and enables you to increase the tool's life.

Electronic Industry.
Silicon nitride has been used to electrically isolate structures and as an adhesive in integrated circuit manufacturing. Silicon nitride is an excellent passivation material for microchips. It has a much better diffusion barrier than silicon dioxide to both water molecules and sodiumions, which are two of the most common sources of corrosion and instabilities in microelectronics. It can be used in an analog chip capacitor as a dielectric to separate polysilicon layer.
