Silicon Metal 2202 With High Performance

The main component of metal silicon 2202 is silicon, and its content is usually above 99.0%. In addition to silicon, metal silicon 2202 also contains trace impurities such as iron (Fe), aluminum (Al), calcium (Ca), etc., but the content of these impurities is strictly controlled to ensure the high purity of metal silicon 2202. Specifically, the iron content in metal silicon 2202 does not exceed 0.2%, the aluminum content does not exceed 0.2%, and the calcium content does not exceed 0.02%.

Metallic silicon 2202 is produced by smelting, that is, silica (mainly silicon dioxide) is used as raw material, after washing, screening and drying, it is melted at high temperature in a submerged arc furnace with a reducing agent (such as low-ash petroleum coke or asphalt coke, charcoal or wood blocks, etc.). During the smelting process, the silicon element in the silica is reduced to form metallic silicon 2202.

Metal silicon 2202 has a dark grey luster, high melting point, good heat resistance, high resistivity, and high oxidation resistance. These physical properties make metal silicon 2202 widely used in many fields. For example, Metal silicon 2202 is an important raw material for high-purity semiconductor materials and can be used to manufacture polycrystalline silicon and single crystal silicon. These semiconductor materials have a wide range of applications in the photovoltaic industry and the electronics industry, such as the manufacture of solar cells and integrated circuits. Metal silicon 2202 is a key raw material for formulating aluminum alloys. By adding metal silicon 2202, the mechanical properties, corrosion resistance and thermal stability of aluminum alloys can be significantly improved. When smelting special steel and non-ferrous alloys, metallic silicon 2202 is also used as a deoxidizer, helping to improve the quality and performance of steel. Metal silicon 2202 can be used to produce silicone rubber, silicone oil, silicone resin and other organic silicon compounds. These organosilicon compounds are widely used in coatings, plastics, rubber and other industries, such as sealants, lubricants, coating additives, etc.

Metallic silicon 2202 can also be used to make refractory materials, such as silica bricks, siliceous refractory mud, etc. These materials are widely used in high-temperature industrial fields such as steel, nonferrous metals, glass, and cement. In addition, metallic silicon 2202 can also be used to manufacture composite materials such as ferrosilicon alloys and silicon-aluminum alloys, as well as for the preparation of silicides in the chemical industry.
