1.Brief introduction

Black Silicon Carbide is produced in an electric resistance furnace from quartz sand and petroleum coke or anthracite at high temperaturer.

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.
