BLACK SILICON CARBIDE
Black Silicon Carbide is produced at high temperature in an electric resistance type fumace with quarts sand and petroleum coke as its main raw materials. It hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp and has electrical and heat conductivity in some degree. The abrasives made of it are suitable for working on cast iron, non- ferrous metal, rock, leather, rubber, etc. It is also broadly used as refractory material and metallurgical additive.

APPLICATIONS
Black Silicon Carbide is used for cleaning extremely hard surfaces such as tungsten carbide or in cases whereby a deep cutting action is required to remove a thick layer of material such as stone cutting or carving.
