Description:
Silicon carbide powder:
β-SiC powder has high chemical stability, high hardness, high thermal conductivity, low thermal expansion coefficient, wide energy band gap, high electron drift speed, high electron mobility, special resistance temperature characteristics, etc., so it has anti-wear, High temperature resistance, heat shock resistance, corrosion resistance, radiation resistance, good semi-conductive properties and other excellent properties, are widely used in electronics, information, precision processing technology, military, aerospace, advanced refractory materials, special ceramic materials, advanced grinding Materials and reinforcement materials and other fields. Its application scope is mainly divided into the following categories:
Main application of SiC powders:
1. Sintered powder
β-SiC has a very broad application prospect in the market of advanced structural ceramics, functional ceramics and advanced refractory materials. Adding β-SiC to boron carbide ceramic products can improve the toughness of the product while reducing the sintering temperature, thereby greatly improving the performance of boron carbide ceramics.
2. Electronic materials
As a semiconducting material, β-SiC is several times higher than α-Sic. The anti-corona effect of the generator after adding β-SiC is very obvious, and it also has good wear resistance and high temperature resistance. Electronic packaging materials, heaters, heat exchangers, etc. made of β-SiC have high thermal shock resistance, good thermal conductivity, and product performance is much better than other materials.
3. Special coating
Because β-SiC has a diamond structure, the particles are spherical, with super wear resistance, corrosion resistance, super thermal conductivity, low expansion coefficient, etc., so it has a good application in special coatings.
4. Grinding and polishing materials
As a precision grinding and polishing material, β-SiC has a much higher grinding efficiency than white corundum and α-SiC, and it can greatly improve the finish of the product.
Β-SiC grinding paste, grinding fluid, high-precision emery cloth belt and super wear-resistant coating also have good application prospects.
5. High-grade special additives
The addition of β-Sic to polymer composite materials and metal materials can greatly improve their thermal conductivity, reduce expansion coefficient, increase wear resistance, etc., and because the specific gravity of β-SiC is small, it does not affect the structural weight of the material. The performance of high-strength nylon materials, special engineering plastics polyether ether ketone (PEEK), rubber tires, and pressure-resistant lubricating oil are added to the ultrafine β-SiC powder, and its performance is very obvious.
6. Other applications.
Storage Condition:
Beta silicon carbide powder/ cubic SiC powder should be stored in dry, cool and sealing of the environment, can not be exposure to air, keep in dark place. in addition should avoid the heavy pressure, according to ordinary goods transportation.
