Black Silicon Carbide with SiC more than 98%
Description:
Black silicon carbide is produced at high temperature in an electric resistant furnace with quartz sand and petroleum coke as its main raw materials. Excellent raw material make good hardness and toughness, high efficiency and durability. Its hardness is between corundum and synthetic diamond, the mechanical strength is higher than corundum.
