Substantial Top quality Black Silicon Carbide PowEPTAbrasive with Fantastic Consistency
Black silicon carbide (C) is created by petroleum coke, quality silicon sand and appended with salt in an electrical arc furnace at large temperatures. The hardness and brittleness are reduced than that of environmentally friendly silicon carbide. The resources are employed to grind solid iron, non-ferrous metals, rubber, leather-based, plastic, wooden, mineral rocks, and so on. It can also be employed to manufacture substantial-class refractory merchandise.
