Silicon Metal

Silicon Metal (Si Metal) is high purity silicon, also known as industrial silicon or crystalline silicon. Although silicon metal is a non-metal, it has a metallic luster on the outside. It has a high melting point, good heat resistance, high electrical resistivity, and ultra-high oxidation resistance. It is mainly used as an additive for non-ferrous alloys and is an indispensable basic raw material for many high-tech industries.

Application Areas of Silicon Metal

  • Industrial silicon metal powder is often used in the metallurgical casting industry as a non-ferrous alloy additive and silicon steel alloying agent, which can increase the hardenability of steel. Industrial silicon metal powder can also be used as a reducing agent for certain metals, such as new ceramic alloys.
  • In the refractory and powder metallurgy industries, silicon metal is often used in steelmaking furnaces, kilns and kiln furniture to improve the high temperature resistance, wear resistance and oxidation resistance of products.
  • The single crystal silicon produced by purification of industrial silicon can be used in high-tech production fields such as integrated circuits and electronic components.
  • High-purity Si metal is used in many industrial fields. It is used to produce silicon compounds, cells for photovoltaic solar energy, and silicon wafers for electronic semiconductors.
  • High-quality Si metal can also be used to improve the properties of existing aluminum. These properties include casting ability, hardness and strength. Adding silicon metal to aluminum alloy can make the aluminum alloy strong and light.
  • Silicon metal is increasingly used in the automotive industry. For example, as an alternative to replace heavier cast iron parts to reduce the weight of the car body. Among them, automobile engine blocks, tires, and wheel hubs are common parts that use cast aluminum and silicon materials.

Production Process of Silicon Metal

Silicon metal is generally produced by the carbothermic method. The raw material silicon dioxide and the reducing agent charcoal, petroleum coke, etc. are sent into a high-temperature electric furnace for smelting, and the silicon dioxide and various reducing agents undergo a reduction reaction under high temperature heating to obtain silicon metal.

  • Material: Silica
  • Reducing agent: charcoal, petroleum coke, wood chips, low ash coal, etc.
  • Melting equipment: high temperature electric furnace

The purity of silicon metal produced by carbothermal reduction is about 97% to 98% and contains more impurities. Silicon metal of this purity is mostly used in the metallurgical industry. By using the latest refining technology, ZX can produce higher-grade ultra-high-purity silicon metal products with a purity of 99.7%-99.8% to meet the needs of high-tech industries.
