Black silicon carbide is made of high-quality silica as its main raw materials, add quartz sand and coke as additive, smelted by high temperature furnace. Its hardness is between corundum and diamond, the mechanical strength is higher than corundum, brittle and sharp. It can be widely used for abrasive media or as raw material to produce abrasive tools.
