Silicon Carbide
Black Silicon Carbide
It is produced by fusion of quartz sand, anthracite and high-quality silica in electric resistance furnace. The SiC blocks with most compact crystal structure near the core are carefully selected out as raw materials. Through perfect acid and water washing after crushing, the carbon content reduced to the minimum and then the shining pure crystals are obtained. It is brittle and sharp, and has certain conductivity and thermal conductivity.
