Product Description

 

 

Product Description

Silicon carbide includes black silicon carbide and green silicon carbide. Silicon carbide is made by melting quartz sand,Petroleum coke or Coal tar, wood chips, etc. in a high-temperature resistance furnace. Green silicon carbide is made by melting Petroleum coke and high-quality silicon dioxide as the main raw materials, adding salt as the additive, in a resistance furnace at high temperature. Its hardness is between that of corundum and diamond, its mechanical strength is higher than that of corundum, and it is brittle and sharp,has certain conductivity and thermal conductivity. Silicon carbide is one of the most widely used and economical materials, which can be called carborundum or emery carborundum.

 

Product Superiority

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. 
A: Remove oxygen from iron compound. 
B: Adjust the carbon content. 
C: Act as a fuel and provide energy. 
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.

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quartz 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 and sharp and heat conductivity in some degree. The abrasive 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.
