China factory Black silicon carbide grit F40
Black silicon carbide grain (commonly referred to by its chemical formulation of SiC) is a chemical compound comprised of silicon and carbon that results in extremely hard (9 on the Mohs scale) iridescent crystals. Top-rated SiC Silicon Carbide grain raw material of grinding abrasive is a common and widely used raw material for manufacturing coated and bonded abrasives like grinding wheel, sandpaper which suitable for glass, stone, marble, granite applications.
Black silicon carbide sandblasting media for glass and ceramic from HAIXU Abrasive offers superior properties such as:
low density
low thermal expansion, oxidation resistance
excellent chemical resistance
high thermal shock resistance
high wear and hardness resistance
high strength, high-temperature resistance
high-temperature strength
