Black Silicon Carbide


Black Silicon Carbide is produced in an electric resistance furnace from quartz sand and petroleum 

coke or anthracite at high temperature. 

The hardness and sharp particle of this material make it suitable for manufacturing of grinding 

wheels, coated products, wire saws, superior refractory materials and deoxide as well as 

for lapping, polishing and blasting.
