Silicon Carbide (SiC) is produced in an electric furnace at temperatures in excess of 2200 Celsius.

Mohs hardness is 9.2Vickers hardness is 3000-3300 kg/mm, microhardness is 3000-3300kg/mm3.Density generally viewed is 3.20g/ mm3density of heap is 1.2-1.6g/ mm3specific gravity is 3.20~3.25Among abrasives, silicon carbide’s hardness is higher than corundum, and ranked below diamond, CBN and boron carbide. Silicon Carbide can used widely in Metallurgy Industry/ Nonmetal foundry/ Fireproof industry and grinding material industry as its Heat- Resistance corrosion resistance abrasion resistance.
