BLACK SILICON CARBIDE
 
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. The hardness is between fused alumina and synthetic diamond. The mechanical intensity of it is higher than fused alumina. It is sharp and has electrical and heat conductivity in some degree.
 
It is mainly used in functional ceramics, advanced refractory, abrasives and metallurgical materials. For high purity single crystal, used to manufacture semiconductors,manufacture of silicon carbide fibers. Silicon carbide is very hard with excellent thermalconductivity, as a semiconductor and high temperature resistant to oxidation.
