Black silicon carbide has a higher hardness than corundum abrasive. It has sharp knife-edge and friable character as well as good thermal conductivity and quick heat dissipation. The self-sharpening characteristics of black silicon carbide is better than corundum abrasive.
It is suitable for machining and production of ceramics, resin, rubber grinding wheel, refractory material and grinding of gray cast iron, white cast iron, bronze, brass, ore, bone, glass, leather, rubber, plastic and the thermal sensitive material. Black silicon carbide abrasive is also suitable for sandblasting, dry grinding, free grinding as well as cutting and making jewelry, jade, agate and so on.
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.
