Black silicon carbide
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.
Black Silicon Carbide Advantages:
(1) Large melting furnace, longer melting time, lead to more
crystallization, bigger crystals, higher purity and less
(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.
