Black Silicon Carbide Black Silicon Carbide is produced in an electric resistance furnace from quartz sand and petroleum coke or anthracite at high temperatures. The hardness and sharp particle shape of this material make it suitable for manufacturing of grinding wheels, coated products, wire saws, superior refractory materials and deoxidiser as well as for lapping, polishing and blasting

Green Silicon Carbide

Green Silicon Carbide is produced in an electric resistance furnace from quartz sand and petroleum coke or salt at high temperatures. It is semitransparent in green colour with friability, high purity and high hardness. It is suitable for grinding hard, brittle and non-metallic materials such as cemented carbides, optical glass, ceramics, etc.
