Product Description

Green Silicon Carbide is produced in an electric resistance furnace from quartz sand, petroleum coke and salt at high temperature. It's semi-transparet in green color with friability, high purity and high hardness. It's suited for grinding hard, brittle and non-metallic such as cemented carbides, optical glass, ceramics, etc.
