High Top quality Black Silicon Carbide PowEPTAbrasive with Great Regularity
Black silicon carbide (C) is made by petroleum coke, quality silicon sand and appended with salt in an electric arc furnace at higher temperatures. The hardness and brittleness are reduce than that of environmentally friendly silicon carbide. The materials are employed to grind forged iron, non-ferrous metals, rubber, leather-based, plastic, wood, mineral rocks, and so on. It can also be utilised to manufacture substantial-class refractory goods.
