Low Impurity Black Silicon Carbide Powder Carborundum

High High quality Reduced EPTurity Black Silicon Carbide PowEPTCarborundum

Black silicon carbide (C) is developed by petroleum coke, top quality silicon sand and appended with salt in an electrical arc furnace at higher temperatures. The hardness and brittleness are reduce than that of inexperienced silicon carbide. The supplies are used to grind forged iron, non-ferrous metals, rubber, leather, plastic, wooden, mineral rocks, and many others. It can also be used to manufacture high-course refractory products.
