Description
Silicon carbide (carborundum) is made of high-quality silica as its main raw materials, add quartz sand and coke / (Green one add Nacl ) as additive, smelted by high temperature furnace. Its hardness is between corundum and diamond, the mechanical strength is higher than corundum, brittle and sharp.
Characteristic of silicon carbide
- Corrosion resistance, high strength, high hardness.
- Good wear-resisting performance,resist to shock.
- It is a cost-effective substitute for Ferrosilicon.
- It has Multi-functions.
- It costs less than ferrosilicon and carbon combination.
- It has no dust nuisance while feeding the material.
- It can speed up the reaction.
Application of silicon carbide
- Sand wheel making
