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 synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is sharp and has electrical and heat conductivity in some degree.

Application

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.

Specification

Advantages
