Black silicon carbide is made of quartz sand and petroleum coke by high temperature smelting in resistance furnace. Black crystal, micro-hardness HV3100-3280, brittle and sharp, and has a certain electrical and thermal conductivity. The grinding tools are suitable for grinding non-metallic materials such as cast iron, non-ferrous metal, rubber, leather, plastic, wood and ore. In addition, it can also make high - grade refractory, etc.
