Product Introduction
Silicon Carbide Sand is a part of Silicon Carbide . It is most widely used in the modern C, N, B, and other non oxide high technical refractory raw materials. Silicon carbide hardness is very high, the Mohs hardness is a magnitude 9.5, the second only to the world's most hard diamond (10). It with excellent thermal conductivity, is a semiconductor, high temperature resistant to oxidation. Low grade silicon carbide (containing about 85 per cent of the SiC) is an excellent deoxidizing agent, it can accelerate the speed of steel-making, and easy to control the chemical composition, improving steel quality.
The silicon carbide has Green Silicon Carbide and Black Silicon Carbide. Black Silicon carbide used for semiconductor, lightning rod, circuit components, high temperature applications, UV detectors, structural materials, astronomy, disc brakes, clutch, diesel particulate filter, filament pyrometer, ceramic film, cutting tools, heating elements , Nuclear fuel, jewelry, steel, protective gear, catalyst support and other fields.
