Black Silicon carbide
Product Description:
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 synathetic diamond. Mechanical intensity of it is higher than fused alumina. it is brittle and sharp and has electrical and heat conductivity in some degree.
