China Metallurgical Pure Silicon Metal Powder for Aluminium

Product Overviews

Silicon Metal Powder is also called industrial silicon or crystalline silicon,it is dark gray.It’ s characteristics are high melting point, good heat-resisting, high resistivity and excellent anti-oxidation.

The Silicon Metal Powder is manufactured with carbon type reducing agent while silica is smelting in furnace.It is mainly used in production of alloys(especially aluminum alloys), polycrystalline silicon, organic silicon materials and high-grade refactory material.

1.Industrial Silicon Metal Powder is widely applied to the refractory material, powder metallurgy industry so as to improve the products heat-resisting performance, wear resistance and oxidation resistance.

2.In the chemical line of organic silicon, industrial Silicon Metal Powder is basic raw material that composed of high polymer organic silicon, for producing organic monomer, silicon oil, silicon rubber antiseptic. It can improve the porduct’s heat-resisting, electrical insulation, corrosion resistance and waterproof.

3.Industrial Silicon Metal Powder is applied to the manufacture of trichlorosilane and polysilicon which pull into monocrystalline silicon. Silicon slice is widely used in the high-tech fields and is essential raw material to manufacture integrated circuits, electronic components.

4.In metallurgy and foundry industry, industrial Silicon Metal Powder is regarded 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 production of silica sol.

6.For the electronics industry.
