Silicon metal is a gray and shiny semiconductor metal,also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys which smelted from quartz and coke in an electric furnace.

 The classification of metallic silicon is usually classified according to the content of iron, aluminum and calcium, silicon metal can be divided into different grades such as 553, 441, 411, 3303, 2202, and 1101.

The use of Silicon Metal：

1) Improve the heat resistance, wear resistance and oxidation resistance in refractory material and power metallurgy industry

2) Basic raw material that high polymer of organic silicon formatting.

3) 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.

4) In metallurgy and foundry line, industrial silicon powder is regarded as iron base alloy additive, the alloy pharmaceutical of silicon steel, thus improve the steel hardenability.

5) These are used in high-temperature material production in order to manufacture enamels and pottery. These also cater the demands of semiconductor industry by producing ultra-pure silicon wafers.
