Specifications
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.
