Products Description
Metallic silicon, also known as crystalline silicon or industrial silicon, is an important industrial raw material. It is mainly smelted from quartz and coke in an electric furnace. The content of the main component silicon is about 98%. In recent years, there are also metallic silicon with a Si content as high as 99.99%. The remaining impurities are usually iron, aluminum, calcium, etc.
Metal silicon has a wide range of uses. First of all, metal silicon is an important raw material for the production of silicone. Silicone products such as silicone rubber, silicone resin, silicone oil, etc. are widely used in electronics, electrical appliances, medical, cosmetics and other industries due to their unique heat resistance, weather resistance and electrical insulation. For example, silicone rubber is often used to make medical supplies, high-temperature resistant gaskets, etc. due to its good elasticity and high temperature resistance. Secondly, metal silicon also plays an important role in semiconductor manufacturing. It is a key material for manufacturing semiconductor devices such as transistors, integrated circuits, solar cells, etc. Through specific processes, metal silicon can be purified and crystallized to form high-purity single crystal silicon rods for the manufacture of semiconductor chips. It can be said that metal silicon has become the basic pillar industry of the information age. Furthermore, metal silicon is also an important alloy additive. In the production of aluminum alloys, metal silicon can improve the mechanical properties of the alloy, such as strength, hardness and wear resistance. By adjusting the amount of metal silicon added, aluminum alloy products that meet different needs can be produced, which are widely used in aerospace, automobile manufacturing and construction. In addition, silicon copper alloy has good welding performance, is not easy to produce sparks when impacted, has explosion-proof function, and can be used to make storage tanks. Adding silicon to steel to make silicon steel sheets can greatly improve the magnetic conductivity of steel, reduce hysteresis and eddy current losses, and can be used to make transformer and motor cores to improve the performance of transformers and motors.
In addition, metallic silicon is also used in glass manufacturing, optical fiber manufacturing, electronic device packaging, chemical analysis and laboratory research. With the advancement of science and technology and the development of industry, the application prospects of metallic silicon will be broader. In general, metallic silicon plays an important role in many industries due to its unique physical and chemical properties. It is an indispensable basic industrial raw material and has played an important role in promoting the development of modern industry.
