Silica application

The use of metallic silicon

Silicon metal (Si) is an industrial purified elemental silicon, which is mainly used in the production of organosilicon, the preparation of high-purity semiconductor materials and the preparation of alloys with special uses.

(1) Production of silicone rubber, silicone resin, silicone oil and other silicone

Silicone rubber has good elasticity, high temperature resistance, and is used for making medical supplies and high temperature gaskets. Silicone resin is used in the production of insulating paint, high temperature coatings and so on. Silicone oil is a kind of oil, its viscosity is very little affected by temperature, used for the production of advanced lubricants, glazing agents, fluid springs, dielectric liquids, etc., can also be processed into colorless transparent liquid, as an advanced waterproof agent sprayed on the surface of buildings.

Manufacture high-purity semiconductors

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


Silicon aluminum alloy is the largest amount of silicon alloy. Silicon aluminum alloy is a strong composite deoxidizer, which can improve the utilization rate of deoxidizer, purify liquid steel and improve the quality of steel by replacing pure aluminum in steelmaking process. Silicon aluminum alloy density is small, low coefficient of thermal expansion, casting performance and anti-wear performance is good, with its casting alloy castings have a high impact resistance and good high pressure compactness, can greatly improve the service life, commonly used in the production of aerospace vehicles and auto parts.

Silicon copper alloy has good welding performance, and is not easy to produce sparks when impacted, with explosion-proof function, can be used to make storage tanks.

Adding silicon to steel to make silicon steel sheet can greatly improve the magnetic conductivity of steel, reduce hysteresis and eddy current loss, and can be used to manufacture the core of transformers and motors to improve the performance of transformers and motors. With the development of science and technology, the application field of metal silicon will be further expanded.

Silicon dioxide is the manufacturing of glass, quartz glass, water glass, optical fiber, electronic industry important components, optical instruments, crafts and refractory materials, is an important material for scientific research.

Applications of silica: flat glass, glass products, casting sand, glass fiber, ceramic glaze, sand blasting for rust prevention, sand for filtration, flux, refractory and manufacture of Autoclaved Lightweight Concrete. Silica has many uses. Crystals, which are rare in nature, can be used to make important components in the electronics industry, optical instruments and crafts. Silica is an important raw material for manufacturing optical fiber. Generally pure quartz can be used to make quartz glass. The expansion coefficient of quartz glass is very small, equivalent to 1/18 of ordinary glass, can withstand drastic changes in temperature, good acid resistance (except HF), therefore, quartz glass is commonly used to manufacture high temperature resistant chemical instruments. Quartz sand is commonly used as glass raw materials and building materials.
