Black Carborundum Powder For Sand Blasting - China

1 - Black Silicon Carbide

Black Silicon Carbide is produced at high temperature in

an electric resistancetype 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 brittle

and sharp and has electrical and heat conductivity in some

degree.
