Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina.
High quality black silicon carbide is brittle and sharp and has electrical and heat conductivity in some degree. Black silicon carbide for abrasives are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. Black sic is also broadly used as refractory material and metallurgical additive.
