Application

 

1. Silicon powder is widely used in refractory material and powder metallurgy industry,it can improve the products of high temperature resistance, wear resistance and oxidation resistance.
2. In the organic chemical industry, It is the basic material of organic silicon polymer synthesis, it can improve the product of high temperature resistance, electrical insulation, corrosion resistance in the production of silicon monomer, silicone oil, silicone rubber.
3. It could be used in the production of monocrystalline silicon.
4. It can be used in metallurgical and foundry industry as additives to improve the hardenability of steel.
5. It can also be applied to new type of ceramic alloy etc as reducing agent.
