Green Silicon Carbide For Surface treatment
Green silicon carbide is characterized by extreme hardness (Mohs 9.4/2600 Knoop) which only rank after CBN and B4C.
Green Silicon Carbide (SiC) is an extremely hard (Mohs 9.4 / 2600 Knoop) man made mineral that possesses high thermal conductivity and high strength at elevated temperatures (at 1000°C, SiC is 7.5 times stronger than Al2O3). SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C, and it does not melt at normal pressures but instead dissociates at 2600°C.
Green silicon carbide is widely used for surface treatment such as abrasive blasting, sand blasting, lapping, microlapping, polishing, grinding, etc.
Description:
Green Silicon Carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke. It is a synthetic brittle carborundum with high thermal conductivity and high strength which get no decrease in 1000℃ ( 7.5 times stronger than Alumina)
Characteristic:
Extremely high hardness
High wear and hardness resistance
High strength, high temperature resistance
High temperature strength
