Abrasives 
1.Description:
Black Silicon Carbide is produced in an electric resistance furnace from quartz sand and petroleum coke or anthracite at high temperature.
2.Characteristic:
Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina.
3.Application:
The hardness and sharp particle of this material make it suitable for manufacturing of grinding wheels, coated products, wire saws, superior refractory materials and dioxide as well as for lapping, polishing and blasting.
