Product Introduction:
1)Silicon metal is made of quartz and coke in an electric furnace , then smelted into products. The main component of silicon content is about 98% (in recent years, the amount of Si 99.99% is also included in the metal silicon), other impurities: aluminum, calcium and iron.
2) As good constituent element of silicon or aluminum alloys, silicon is contained in vast majority of cast aluminum alloy.
3)Silicon is the raw material of ultrpure silicon in electronic industrial, and electronic devices, ultra pure semiconductor silicon do has the advantages of small volume, light weight, good reliability and long service life etc..
4)Content classification of silicon metal usually depends on impurity composition of iron, aluminum, calcium. According to the content of Fe, aluminum, calcium, silicon metal can be divided into different grades, such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and so on.
5)Industrial silicon metal, usually made in the furnace during the reduction of carbon dioxide. Chemical reaction equation: SiO2 + 2C→ Si + 2CO for the 97~98% silicon purity, called silicon metal. Then it melts recrystallization, with acid to remove impurities, the purity of silicon metal 99.7~99.8%.
6)Most metallurgical Silicon Metal is used as an alloying agent in the aluminium industry due to its ability to increase the strength of aluminium.Demand from the aluminium industry has grown steadily in recent years due to increased usage of aluminium in structural engineering,aircraft manufacture and the automotive industry.
7) Its CAS number is [7440-21-3].
Usage of Metal Silicon:
1)As an alloying element for aluminium alloys for casting and extrusions;
2)As the basic raw material for silicons produced by the chemical industry.
3)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 powder is basic raw material that high polymer of organic silicon formatting
6) Industrial silicon 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 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
