Black silicon carbide for mental surface treatment
Description
Silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond, so it always be applied in mental surface treatment sector.
Characteristic of silicon carbide
- High hardness
- Good thermal conductivity
- Thermal expansion coefficient is small
- Wear resistance
- Sharp
Application of silicon carbide
- Mental surface polishing
- Rust removal
