Product Description
Silicon Metal is also called industrial silicon or crystalline silicon.It is silver gray
with metallic luster, when be processed into powder the coloure si dark grey. It has high
melting point, good heat resistance and high resistivity.It is usually used in electro,
metallurgy and chemical industry. It is the indispensable essential raw material in the hi-
tech industry.
1)Silicon Metal ,as an alloying element for aluminium alloys for casting and extrusions;
2)Silicon Metal 411 ,As the basic raw material for silicons produced by the chemical industry.
3)Silicon Metal,As an alloy element in smelting ferro silicon in the steel industry, and as a reducing agent in many kinds of metal smelting.
4) Widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance.
5) In the chemical line of organic silicon, industrial silicon metal powder is basic raw material that high polymer of organic silicon formatting
6) Industrial silicon metal powder is sublimated into monocrystalline silicon, which is widely used in highttech field as an essential raw material for integrated circuit and electronic element.
7) In metallurgy and foundry line, industrial silicon metal powder is regarded as to be iron base alloy additive, the alloy pharmaceutical of silicon steel, thus improve the steel hardenability.
8) These are used in hightemperature material production in order to manufacture enamels and pottery. These also cater the demands of semiconductor industry by producing ultra-pure silicon wafers
