DESCRIPTION
Silicon Carbide is a kind of non-metallic carbide combined with silicon and carbon. Through raw materials such as quartz sand, petroleum coke, wood chips, etc, it is smelted by an electric furnace at high temperature, and its hardness is second only to diamond, with a hardness of 9.5. Common silicon carbide is black or black-blue in appearance, which has the advantages of stable chemical properties, good wear resistance, and high thermal conductivity.
