Large Top quality Black Silicon Carbide PowEPTAbrasive with Fantastic Regularity
Black silicon carbide (C) is made by petroleum coke, quality silicon sand and appended with salt in an electric powered arc furnace at substantial temperatures. The hardness and brittleness are decrease than that of environmentally friendly silicon carbide. The materials are employed to grind cast iron, non-ferrous metals, rubber, leather-based, plastic, wood, mineral rocks, and so forth. It can also be utilized to manufacture high-class refractory products.
