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. It is
sharp and has electrical and heat conductivity in some degree.
Silicon carbide is widly used as refractory material and metallurgical material. It is one of the mainly materials to produce SIC refractory bricks. Black SIC is one of the most important materials in steel producing as desoxidant.

Abrasive black silicon carbide powders are the perfect material that specifically manufactured to be used for general abrasive applications in bonded abrasive tools, lapping and polishing processes. While silicon carbide has lower hardness and abrasive capacity than diamond and boron carbide, it is widely used for grinding non-ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important
