Black Silicon Carbide
Black Silicon Carbide
Black Silicon Carbide is the product of silicon quartz sand and petroleum coke electrofused at high temperature in an electrical resistance furnace. The grains of Black Silicon Carbide are hexagonal crystals that are extremely hard, sharp, and friable, and have outstanding electrical and thermal conductivity and low thermal expansion.

Description
Black Silicon Carbide is mainly made from quartz sand, petroleum coke as the main raw materials and smelted by electric resistance furnace at high temperature. During this high temperature process the crystalline is formed, the grains are extremely hard, sharp, and friable, with many excellent features like as follows:
Low density
High hardness
Good high temperature strength
Oxidation resistance
Excellent thermal shock resistance
High hardness and wear resistance
Excellent chemical resistance
Low thermal expansion and high thermal conductivity
