Green Silicon Carbide Sand for Abrasives,Blasting,Grinding,Ceramic,Rust Removal,Surface Treatment, Floor Coating,Abrasion Resistant Layer
Green Silicon Carbide 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. .
