Black Silicon Carbide
Black silicon carbide is produced from quarts sand and coke or coal as its main raw material, melted at high temperature in an electric arc furnace. Its hardness is between fused Alumina and synthetic diamond, while mechanical intensity is higher than fused Alumina. It is brittle and sharp. The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also widely used as refractory material and Metallurgical additive.
Advantages
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.
