1. Black Silicon Carbide 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 brittle and sharp
and has electrical and heat conductivity in some degree. The abrasives made of it are suitable for
working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also broadly used as refractory
material and metallurgical additive.

3. Black silicon carbide usage:
(1) Large melting furnace, longer melting time, lead to more crystallization, bigger crystals,
higher purity and less impurities.
(2) Good hardness, longer life.
(3) Chemical washed and water washed, good cleanness.
(4) Special treated products get higher purity, better toughness, and better grinding effect.
