Product Description
Factory Price Black Green Silicon Carbide Powder with Great Quality, More Specifications Customizable
Black silicon carbide (C) is produced by petroleum coke, quality silicon sand and appended with salt in an electric arc furnace at high temperatures. The hardness and brittleness are lower than that of green silicon carbide. The materials are used to grind cast iron, non-ferrous metals, rubber, leather, plastic, wood, mineral rocks, etc. It can also be used to manufacture high-class refractory products.
Note: Special requirements on chemical composition and other terms can be satisfied through discussion.

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.
