About Silicon Carbide Nanoparticles Nano SiC Powder:
Silicon Carbide( SiC ) Nanopowder, A grey-white powder composed of silicon carbide particles with diameters averaging 40nm. This material is known for its stability, refractory properties, wear resistance, thermal conductivity, small thermal expansion coefficient, and resistance to oxidation at high temperatures. These traits make it ideal for applications across a wide range of domains, with more being uncovered by the research of academics and engineers with each passing year.
As an important refractory material, nano-SiC is not flammable and chemically stable at high temperatures. Research on this topic shows that SiC nano paper is very stable when heated with an alcohol lamp. Due to the properties of SiC material, SiC nano paper has excellent non-combustibility, fire resistance and thermal stability. This independent feature has enlightening potential applications in improving the ablation resistance of high-temperature ceramic composites and high-temperature exhaust gas filtration and dust filters. Feel free to send an inquiry to get the latest price if you would like to buy Silicon Carbide Nanoparticles Nano SiC Powder in bulk.

Product Performance of Silicon Carbide Nanoparticles Nano SiC Powder:

Silicon carbide nanoparticles ( CAS 409-21-2 ) has high purity, small particle size, uniform distribution, large specific surface area, high surface activity, and low bulk density. It has excellent mechanical, thermal, electrical, and chemical properties. It has high hardness, high wear resistance, and good Self-lubricating, high thermal conductivity, low thermal expansion coefficient and high-temperature strength.

How is Silicon Carbide Nanoparticles Nano SiC Powder produced?
An organic-inorganic precursor is synthesized from industrial silica sol and water-soluble phenolic resin to prepare silicon carbide nanopowder. After high-temperature heat treatment, silicon carbide nanopowder is prepared through a carbothermic reduction reaction. The thermal decomposition process and preparation process of the precursor are analyzed. Silicon carbide nanopowder has more applications due to its smaller size.
Studies have shown that the preparation process of the product is simple, and it is a mixture of high-purity nano silicon carbide powder and silicon carbide whiskers. In the research of researchers from Northwestern Polytechnical University, NANO-SiC powder was synthesized by CARBO-THERMAL reduction method and its dielectric parameters in the frequency range of 8.2 to 12.4 GHz were measured. By changing the aluminum content and reaction atmosphere, β, 12H and 21R silicon carbide powders are obtained. Although the solid solution of Al and N will resist the resistance of SiC powder, the relative dielectric constant ε’r=30-50 of SiC powder is much higher than that of α-SiC powder, and the dielectric loss tangent (tgδ=~0.7). Polyacrylate/nano-SiO2 composite material has excellent film-forming properties, weather resistance, adhesion and high hardness, abrasion resistance and ultraviolet resistance of inorganic nanopowder.

Application of Silicon Carbide Nanoparticles Nano SiC Powder:
Silicon carbide nanopowder has become the most commonly used material in structural ceramic applications. As an alternative to thermal expansion, higher strength weight percentage, higher variability, hardness, wear resistance and corrosion resistance, and most importantly, maintaining elasticity at temperatures up to 1650°C, these characteristics lead to a wide range of applications.
This nanopowder is used extensively in the production of high-frequency ceramic, heat resistant ceramic parts, textile ceramics,
and various other ceramic materials.
This material can be used to produce various abrasive surfaces and substances, including polishing abrasives, the surfaces of grinding tools, actual grinding materials, and related products.
3.Heat-resistant devices
High-temperature spray nozzles such as those used in aeronautics, heating elements, sealing valves, and other mechanical products intended to resist extreme temperatures utilize this material in their construction.
4.Rubber production
Rubber tires and other rubbers exposed to high temperatures and large amounts of wear take advantage of the properties of this nanoparticle.
5.Specialty coatings
Like many nanomaterials, silicon carbide can be used to produce countless specialty coatings, imparting some or all of its traits to the coated surface. Applications of this nature include abrasive surfaces, mirror coatings for UV resistance, and many others.
6.Their operations are more suitable for low-temperature wear than for high-temperature behavior. The uses of SiC include sandblasting injectors, automotive water pump seals, bearings, pump components and extrusion dies. These dies use silicon for their high hardness, wear-resistance and carbide corrosion resistance.
7.The structural use at high temperature extends from the throat of the rocket jet to the furnace roll, and the components of the exchange exchanger tube are made of silicon carbide with a combination of high strain rate, hardness and high-temperature stability.
8.This kind of heat-resistant ceramic has thermal shock resistance and high asynchrony, which is very suitable for manufacturing furnace lining and accessories.
9.It is used to make pencils, sandpaper, ceramics and as an abrasive for cutting or polishing.
10.Silicon carbide nanopowder is also used in the production of aerial mirrors. This material is used because it is very hard and resistant to thermal shock. Silicon carbide can also prevent mechanical fatigue, absorb moisture and cause space radiation.
11.Because it has high mechanical strength and lightweight. It limits the impact of armor weight on user performance (mobility and fuel consumption).
12.Because of its special characteristics, silicon carbide nanopowder is an alternative material in a variety of electronic applications, including chemical inertia at all temperatures, thermal shock resistance, hardness and abrasion sintering. Its main application in this industry is in the manufacture of stoves and process components used in the semiconductor industry as well as in electric field classification and surge protection.
