BLACK SILICON CARBIDE GRITS

1. 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.

2. Application:

♦As the abrasive: used for abrasive, such as grinding wheels, whetstone, grinding
wheel, sand tiles etc.

♦As the metallurgical deoxidizer and high temperature material.

Four main application areas of SiC: functional ceramics, advanced refractory,
abrasives and metallurgical materials.

♦High purity single crystal, used to manufacture semiconductors, manufacture of
silicon carbide fibers.

♦Silicon carbide is very hard, with excellent thermal conductivity, as a semiconductor
and high temperature resistant to oxidation.
