Black silicon carbide is quartz sand, petroleum coke and quality silica as the main raw material in electric arc furnace smelting. Its hardness between corundum and diamond, the mechanical strength is higher than corundum, brittle and sharp. Black silicon carbide SiC containing approximately 98.5% higher than its toughness green silicon carbide, mostly for processing low tensile strength of the material, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals.
