silicon carbide index in Minerals & Metallurgy

Description

 

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

Green silicon carbide (GC) is widely used to make coated abrasives or . It also is used to produce advanced refractory products, electric products, electronic devices, etc.

  The workable material by GC grinding wheel:

1. Hard alloy, glass, ceramic and non-metallic materials;

2. Semiconducting material, high-temperature silicon carbide heating element, far infrared source base material, etc.  

 

 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. 
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.
