Boride Powder and its application

/ / no Comments

What is Borides Powder? Boride Poudre The boron is combined with metals or non-metals. It is usually a mesenchymal substance and does not conform to valence rules. Except for zinc (Zn), cadmium (Cd), mercury (Hg), gallium (Ga), indium (In), thallium (Tl), germanium (Ge), tin (Sn), lead (Pb), bismuth (Bi).
Borides powder can be formed from other metals. These crystals are hard and have melting points. Chemically stable, they cannot be dissolved with hot concentrated nitric. They can be combined directly with elements, or by reducing oxides and active metals. They can be used as superconducting, abrasive and refractory materials.
Boron, a light metal, forms Borides Powder with the transition metals. The compounds with high melting point are formed from elements in groups IVA and VA. The structural characteristics of the boric atom determine the crystallographic structure of boride. Borides Powder's chemical stability gradually decreases as it moves from IVA towards VIA. Borides Powders TiB2, ZrB2, or HfB2 are the most stable.
Boride Powder crystal structure
Between boron atoms, the lattice forms structural units that include single bonds and double bonds. Also, spatial frameworks such as networks are created. As the proportion of boron increases in the boride, the structure unit becomes more complex.
In general, the more complex boron's atomic structure, the less likely boron is to be hydrolyzed. It also has a stronger resistance to oxidation and nitrogen.
In transition metal Borides Powder the chemical bond is between the metal and the boron. This electronic bond transforms the boron into a positively-charged ion.

Borides Powder: Preparation methods
Borides Powders are made by the main method of refractory metal Borides powder manufacturing.
1.The reaction formula between metal and boron at high temperature is
Me+B----MeB
Reducing metal oxide and boric acid with carbon is
2MeO+B2O3+5C---2MeB+5CO
Aluminum (silicon, Magnesium) Thermal method. Aluminium or silicon, magnesium reduces the oxides to generate metals and boron.
MeO + B2O3 + AI (Si,Mg )---MeB+Al oxide
Reducing metal oxides by boron carburide and carbon
4MeO+B4C+3C---4MeB+4CO
Reduce refractory metal oxides by using boron
xMeO+2xB---xMeB+(BO)x
Borides Powder: Use and nature
Boride is known for its high conductivity. It also has a high melting temperature, high hardness and high stability. The oxidation resistance at high temperatures of boride metals is based upon group IVB. Boride has the highest oxidation resistance.
Borides Powder do not react with humid air and dilute hydrochloric acids, but they do dissolve in nitric. Borides Powders are mainly metals with high conductivity, positive temperature coefficient of resistence and a metallic appearance. Borides Powders Ti, Zr, Hf, and Zr have better conductivity compared to their metals.
The creep resistance is excellent, which makes it a good choice for materials used in gas turbines or rockets. They can also resist deformation and corrosion and are resistant to heat shock. Borides Powder, carbides, nitrides, or other alloys or cermets can be used as sample holders for high temperature material testing machines and instruments, bearings, structural parts for nuclear energy devices, and components for aviation equipment.

What is Hafnium Diboride Powder?

/ / no Comments

What is it? Hafnium Diboride Powder ? Hafnium boreide is a gray-colored crystal with metallic luster. It has high conductivity, and stable chemical property. It is indistinguishable from all other chemical reagents at room temperature, with the exception of hydrofluoric acids. It can be prepared by heating hafnium oxide, boron carbonide, and carbon powder. It is used to make superalloys.
The key features of Hafnium Diboride Powder
Hafnium Diboride has a high melting point, high hardness and excellent electrical and thermal conductivity. It also exhibits good neutron absorption properties. It can be used to make electrode materials, neutron absorption materials, ultra-high-temperature materials, and super-hard materials.

Applications of Hafnium Diboride Pulver
1. Hafnium Diboride in wear-resistant coats Because of its exceptional fire resistance, it can also be used in ultra high temperature composite materials (SiC) with silicon carbide. This material is more resistant to oxidation when it has been combined with silicon carbide.
2. Temperature and pressure determine the resistance to oxidation of hafnium-diboride. At 1500 degrees Celsius and 1 atmosphere pressure, a protective oxide of hafniumoxide is formed. HfB2's oxidation resistance will decrease significantly if it is heated above 1600 degrees Celsius and the pressure drops below one atm. These conditions will cause the boiling temperature for B2O3 (another oxidation product of HfB2) to exceed 1400°C. A protective oxide layer will then form.
3. Because of its strength and thermal characteristics, HfB2 can be used in ultra high-speed reentry vehicle, such as heat shields, for intercontinental ballistic missiles, or aerodynamic fronts. HfB2 forms aerodynamic shapes unlike composite and polymers, and does not ablate during reentry.
4. Hafnium Diboride has been also investigated as a possibility for new materials in nuclear reactor control rods.
5. Hafnium-diboride is being investigated as a diffusion barrier for microchips. If the synthesis is correct the barrier thickness could be less than 7 nanometers. The supplier Hafnium Diboride Powder

The Applications of Aluminum Diboride Powder

/ / no Comments

Overview of Aluminum Diboride Powder
Aluminum boride AlB2 (or AlB2) is a binary mixture made of aluminum and boron. It is a red solid at normal pressure and temperature. It loses its glossy surface when heated. It is stable when it is in cold dilute acid. However, it will decompose in hot hydrochloric or nitric acid. Mixing fine powders of aluminum or boron and heating them after reacting.
It is one among two compounds of aluminum, boron and AlB12, also known as aluminum boreide. AlB12, a monoclinic crystal that is black and shiny with a specific gravity of 2.55 (18degC), It is insoluble when it comes into contact with acid, water, and alkali. It is formed by melting aluminum, sulfur and boron trioxide. AlB2 has a single crystal that is parallel to the hexagonal structure of the matrix.
Aluminum Boride is a dangerous substance as it reacts to acid and hydrogen to make toxic gases. To release borane, and aluminum chloride, it reacts to hydrochloric acid.
AlB2 (alluminium diboride) has a structure that is very similar to graphite flakes. It is found between the B and B atoms of aluminum diboride (AlB2), which is very similar with the structure in magnesium diboride. AlB 2 single crystal shows metal conductivity along an angle parallel to the hexagonal plan of the substrate.
The AlB2 crystal structure is used to describe intermetallic compound prototype structures. There are many structures in the AlB2 family.

What is Silicon Boride Powder?

/ / no Comments

Introduction to Silicon Boride Powder Silicon Boride This lightweight ceramic compound is also known as boron silicide. It is composed of silicon andboron. There are three types of silicon triboride.
Silicon hexaboride is also known as hexaboron Silicide. It's a glossy, black-gray powder. SiB6 is its chemical formula. The molecular weight of SiB6 is 92.95. The melting point is 2200. It is roughly the same hardness as ruby or diamond. Silicon hexaboride is capable of conducting electricity. It is insoluble when water is used. It can be oxidized when heated in chlorine or water vapor.

Silicon Boride Powder's Physicochemical Property
The SiB6 crystal structure includes interconnected icosahedrons, polyhedrons that have 20 faces and icosahedrons that have 26 faces. It also contains isolated silicon and bore atoms.
It is insoluble when it comes into contact with water, and is resistant to oxidation and thermal shock. It has high strength, stability, and resistance to thermal shock. It is more efficient than boron caride in grinding.
Surface oxidation is caused by SiB6 being heated in oxygen or air. SiB6 can then be eroded at high temperatures using boiling sulfuric and fluorine, chlorine, and bromine. Borides can be used as electrical conductors. Hexamborides are low in thermal expansion and have high thermal neutron cross sections.
