Substantial Quality Black Silicon Carbide PowEPTAbrasive with Great Regularity
Black silicon carbide (C) is produced by petroleum coke, high quality silicon sand and appended with salt in an electric arc furnace at high temperatures. The hardness and brittleness are decrease than that of green silicon carbide. The resources are used to grind solid iron, non-ferrous metals, rubber, leather-based, plastic, wooden, mineral rocks, and so forth. It can also be utilised to manufacture higher-class refractory items.
