Raw Materials Silicon Carbide Graphite Crucibles Supplier

Silicon Carbide, also known as carborundum, is produced by melting a mixture of sillica sand and cokes in ultra high power electric furnaces. Silicon Carbide is chemically stable and has high corrosion resistance, which makes it hard to corrode from exposure to alkali or acid. Silicon carbide is also characterized by its high hardness, outstanding heat resistance, low thermal expansion, resistance to chemical reaction, and ability to function as a semiconductor.
