Black silicon carbide is produced at high temperature in electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between Aluminum Oxide and Synthetic Diamond. Mechanical intensity of it is higher than Aluminum Oxide. It is brittle and sharp and has electrical and heat conductivity in some degree. It is suitable for make grinding wheels, cutting wheels, mounted wheels, oil stone, abrasive media, and also suitable for surface gringing, lapping or polishing. The abrasive products made of it are suitable for working on Cast Iron, Non-ferrous Metal, Rock, Leather, Rubber, Wood, ceramic, etc. It is also broadly used as high-grade refractory material and metallurgical additive.
