Black Silicon Carbide

Silicon carbide is a man-made material manufactured in electric resistance type furnace with quarts sand and petroleum coke as its main raw marterials. Silicon carbide is an extremely hard material (Mohs hardness 9.25), is chemically inert and does not melt. it is widely used grinding wheels,and also used as refractory material and metallurgical additive.
