Higher Good quality Black Silicon Carbide PowEPTAbrasive with Excellent Consistency
Black silicon carbide (C) is produced by petroleum coke, good quality silicon sand and appended with salt in an electric arc furnace at higher temperatures. The hardness and brittleness are lower than that of green silicon carbide. The components are used to grind cast iron, non-ferrous metals, rubber, leather-based, plastic, wooden, mineral rocks, and so on. It can also be used to manufacture substantial-class refractory merchandise.
