Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarters of sand and petroleum coke. Its grains are hexagonal black crystals with sharp and gragile properties. It has high extreme hardness, high electrical and thermal conductivity, low thermal expansion.
Suitable for agglomerated abrasives, such as stone grinding and polishing, low tensile strength metal processing, and non-metallic materials, such as gray cast iron, brass, aluminum, stone, leather, rubber, sandblasting, metallurgy, refractory, etc.
