97.5% Min Industrial Silicon Metal/Silicon Metal for Refractory Welding Castable Motar Materials Silicon

Product Description

Characteristics:
Silicon metal powder, is silver grey or dark grey powder with metal luster. With high melting point, good heat resistance, and high resistivity and anti-oxidation, it is an indispensable raw material for many high-tech industries, called "industrial monosodium glutamate"used as the indispensable basic raw materials of a lot of high-tech products.

Application
1). Industrial silicon metal powder is widely used for refractories and powder metallurgy to improve thermostability, wear resistance and inoxidizability of products. Its products are widely used in steel furnaces, kilns and kiln furniture.
 

2).In organosilicon chemical industry, industrial silicon metal powder is used as basic material for organosilicon polymer synthesis to produce silicon monomer, silicone oil, and silicon rubber preservative, so as to improve thermostability, electric insulativity, corrosion resistance and waterproofing of products.
 

3).Industrial silicon metal powder is applied to the manufacturer of trichlorosilane and polysilicon which pull into monocrystalline silicon .silicon silice is widely used in the hi-tech fields and is essential raw material to manufacture integrated circuits,electronic components.

 

4)In metallurgy and foundry industry, industrial silica powder is used as non-iron-based alloy additives and silicon steel alloying agent to improve hardenability.The industrial silicon powder can also be used as the reducing agent of some metal and in new-type ceramic alloy.etc.
 

5)For the producion of silica sol.
 

6)For the electronics industry. The common specification is 40-120mesh,200mesh,325mesh,800mesh,etc. According to the needs of customer,we can supply the different particle size range.
