The use of Silicon metal

Weden Metal Co.,Limited | Updated: Feb 01, 2018

Silicon Metal (Si) is an industrial pure elemental silicon, mainly for the production of silicones, made of high purity semiconductor materials and formulated with special purpose alloys.


(1) production of silicone rubber, silicone, silicone and other silicones

  Silicone rubber elasticity, high temperature, for the production of medical supplies, high temperature washers and so on.

  Silicon for the production of insulating paint, high temperature coatings.

  Silicon oil is an oily substance whose viscosity is very little influenced by the temperature. It is used for the production of advanced lubricants, polishes, fluid springs, dielectric fluids, etc. It can also be processed into a colorless and transparent liquid and sprayed as an advanced water repellent On the building surface.


(2) manufacture of high-purity semiconductor

  Modern large-scale integrated circuits are almost always made of high-purity metal silicon, and high purity silicon metal is the main raw material for the production of optical fibers. It can be said that silicon metal has become the basic pillar industry in the information age.


(3) Preparation of alloy

  Silicon-aluminum alloy is the largest amount of silicon alloy. Silicon aluminum alloy is a strong compound deoxidizer, instead of pure aluminum in the steelmaking process can improve the utilization of deoxidizer, and can purify the molten steel to improve the quality of steel. Silicon-aluminum alloy with small density, low coefficient of thermal expansion, good casting performance and anti-wear performance, with its cast alloy castings with high impact resistance and high pressure densification, can greatly enhance the service life, commonly used in the production of spacecraft And auto parts.

  Silicon copper alloy has good welding performance, and not easy to produce sparks in the impact, with explosion-proof function, can be used for making storage tanks.

Silicon steel made of silicon steel, can greatly improve the permeability of steel, reducing hysteresis and eddy current losses, can be used to make the transformer and the motor core, improve the performance of transformers and motors.

With the development of science and technology, the application of silicon metal will be further expanded.

  The main producing areas of silicon metal: silicon metal is mainly distributed in Yunnan, Sichuan, Guizhou, Guangxi, Central China's Hunan, Hubei, East China's Fujian region in the southwest, northeastern region is mainly Heihe, Linjiang, Heilongjiang, Jilin and Liaoning, Inner Mongolia, including Qinghai, Shaanxi and other places also have manufacturers.

  The first two are low-grade metal silicon, 3303 is a high grade, high purity, it can be used to make polysilicon
