Black Silicon Carbide

Silicon Carbide (SiC), also known as Emery, is a high-performance material made by high-temperature smelting of high-quality quartz sand and petroleum coke in an electric furnace. It has a hardness just below diamond and mechanical strength superior to alumina. Silicon carbide is a covalent-bonded material, with both silicon (Si) and carbon (C) forming four bonds. Its unique network structure gives it high strength, excellent high-temperature resistance, exceptional wear resistance, and superior resistance to acid and alkali corrosion.
