SILICON Powder

A. 2N: Si≥99%

i-553, Si-441, Si-421, Si-3303, Si-2202

B. 3N: Si≥99.9%

C. 4N: Si≥99.99%

D. 5N polysi: Si≥99.999% Fe≤0.1 ppm, Al≤0.1 ppm, Ca≤0.05 ppm, B≤2 ppm, P≤3 ppm

A. Purity with 99.9% is grinded from silicon metal blocks and are gray-colored and have metallic luster. It is widely used in refractory materials, basic raw materials of silicone, integrated circuit components, powder metallurgy, construction engineering, water conservancy engineering and other fields.

B. Purity with>=99.9% is purified from lower purity. It is widely used in refractory materials and refractory ceramics, sputtering target coating etc.

A. Silicon metal powder is widely used in refractory and powder metallurgy industries to improve the product's high temperature resistance, wear resistance and oxidation resistance. Its products are widely used in steelmaking furnace, kiln, kiln furniture.

B. In the silicone industry, silicon metal powder is the basic raw material for the synthesis of silicone macromolecule. For example, it is used to produce silicone monomer, silicone oil and silicone rubber preservative, so as to improve the high temperature resistance, electrical insulation, corrosion resistance, waterproof and other characteristics of the product.

C. Silicon metal powder is pulled into monocrystalline silicon, and the processed silicon wafer.

A. Refractory field: firebrick, etc;

B. Polysilicon field: solar photovoltaic and semiconductor materials;

C. Silicone field: silicone oil, silicone rubber, silane coupling agent, etc;

D. Polysilicon field: solar photovoltaic materials and semiconductor materials;

E. Silica sol field: silicone resin, etc.

A. into 1mt big bag

B. into 25kg bag, and 40 bags into a big bag or onto a pallet
