Product Description
Green silicon carbide (GC) is produced by petroleum coke, quality silicon sand and appended with salt in an electric arc furnace at high temperatures. The hardness is higher than synthetic corundum, but lower than diamond. Mechanical strength is higher than corundum. The materials are used to grind hard and brittle metal, non-ferrous metals like copper, brass, aluminum and magnesium, and non-metallic materials such as gem, optical glass, ceramics, etc.
