Green Silicon Carbide Green Diamond 600 Mesh for Graphite Blades—-Product introduce
Green SiC is an extremely hard (Knoop 2600 or Mohs 9.4) man made mineral that possesses high thermal conductivity (100 W/m-K).
It also has high strength at elevated temperatures (at 1000°C, Green SiC is 7.5 times stronger than Al2O3).
Green 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 2815.5°C.
