metal silicon powder

　　Metal silicon powder is powdered silicon powder produced by grinding and processing metal silicon (industrial silicon).

　　Metallic silicon is also called crystalline silicon or industrial silicon, and its main use is as an additive for non-ferrous alloys. Industrial silicon is also used as an alloying agent for demanding silicon steel, as a deoxidizer for smelting special steel grades and non-ferrous alloys. After a series of process treatments, industrial silicon can be drawn into monocrystalline silicon for use in the electronics industry.

　　Silicon metal properties

　　The main component of silicon metal is silicon, so it has similar properties to silicon. The properties of metal silicon are similar to those of germanium, lead, and tin, and have semiconductor properties.

　　Silicon metal classification

　　The classification of metallic silicon is usually classified according to the content of the three main impurities of iron, aluminum, and calcium contained in the metallic silicon component. According to the content of iron, aluminum and calcium in silicon metal, silicon metal can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101.

　　Silicon metal add-on products

　　Including silicon powder, side skin silicon, black skin silicon, metal silicon slag, etc. Among them, silica powder is also called silica fume, micro silica fume or silica fume, which is widely used in refractory materials and concrete industries.

　　Use of metal silicon powder

　　　　 1. Metal silicon powder is widely used in refractory materials and powder metallurgy industries to improve the high temperature resistance, wear resistance and oxidation resistance of the products. Its products are widely used in steelmaking furnaces, kilns and kiln furniture.

　　        2. In the organic silicon chemical industry, metal silicon powder is the basic raw material for organic silicon polymer synthesis, such as the production of silicon monomers, silicon oil, and silicon rubber preservatives, thereby improving the high temperature resistance, electrical insulation and corrosion resistance of the product Features such as resistance, corrosion resistance, and water resistance.

　　　　 3. Metal silicon powder is drawn into monocrystalline silicon. The processed silicon wafers are widely used in high-tech fields and are essential raw materials for integrated circuits and electronic components.

　　　　 4. In the metallurgical casting industry, metal silicon powder is used as a non-ferrous alloy additive and silicon steel alloying agent to improve the hardenability of steel. Industrial silicon powder can also be used as a reducing agent for certain metals and for new ceramic alloys.
