Characteristics:
- SiC is an extremely hard (Mohs 9.4 / 2600 Knoop) mineral that possesses high thermal conductivity and high strength at elevated temperatures
- Green SIC is made from Silica sand and coke, and is extremely pure. Hexagonally shaped, it breaks into very sharp particles. Green SiC is harder than black, coming in at a 9.4 Mohs and 2600 on the Knoop scale.
- SiC is produced in electrical internal resistance furnaces from very high purity silica sand and petroleum coke.
- Extremely hard (Mohs hardness 9.25)
- High thermal conductivity
- Low coefficient of thermal expansion
- Thermal Shock and abrasion resistant.
Applications :
- It is suitable for grinding high-speed, high carbon steel
- High-grade refractory materials
- Abrasives tool
- Grinding and polishing
