Black 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. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp has electrical and heat conductivity in some degree.
The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also broadly used as refractory material and metallurgical additive.
Applications
1. Metallurgical deoxidizer.
2. High temperature resistant materials.
3. As abrasive, abrasive tools can be used to such as grinding wheels, whetstones, grinding head, sand tile etc.
Advantages
1. Corrosion resistance, high strength, high hardness.
2. Good wear-resisting performance,resist to shock.
3. It is a cost-effective substitute for Ferrosilicon.
4. It has Multi-functions.
5. It costs less than ferrosilicon and carbon combination.
6. It has no dust nuisance while feeding the material.
7. It can speed up the reaction.
