Silicon carbide (carborundum) is made of high-quality silica as its main raw materials, add quartz sand and coke / (Green one add Nacl ) as additive, smelted by high temperature furnace. Its hardness is between corundum and diamond, the mechanical strength is higher than corundum, brittle and sharp.
