SiCl4

Four silicon chloride, alias silicon chloride, chemical formula is SiCl4, is the synthesis of organosilicon polymer compounds and the production of high-purity silicon important raw materials, in 1823 by Yons Becelius for the first time found. Four silicon chloride at room temperature is colorless or light yellow smoke liquid, pungent odor, easy to tide solution, can be dissolved in benzene, chloroform, petroleum ether

Chemical name or trade name: Silicon tetrachloride

Product number: SLSL001

CAS No.: 10026-04-7

Alias: four chloro silane; STC

STC; Tetrachlorosilane


High purity four silicon chloride is colorless transparent liquid, non-toxic, slightly lower purity of slightly yellow or light yellow, with choking odor. Under normal temperature and pressure, the density is 1.48, the melting point is -70, and the boiling point is 57.6. The boiling point increases with the increase of pressure. Silicic acid and hydrogen chloride are hydrolyzed in moist air. In water, the hydrolysis is very intense, and also can react with alcohols. It is widely used in the manufacture of organosilicon compounds, such as silicate ester, organic silicone oil, high temperature insulating paint, silicone resin, silicone rubber and heat-resistant pad lining material. High purity four silicon chloride is used to make polycrystalline silicon, high-purity silicon dioxide and inorganic silicon compounds, quartz fiber material. The metallurgical industry is used to make corrosion resistant ferrosilicon. Foundry industry used as release agent. It is an indispensable chemical raw material in large industrial production.

The company uses exclusive advanced technology to produce four purity silicon chloride products with different purity grades, providing stable and reliable raw material sources for four chlorinated silicon users in related industries.

The new production chain with the characteristics of green, environmental protection, energy saving and high output benefit. In the production process, no damage to the environment of the material, and fully recycling, as a model of energy saving and emission reduction in the industry.

In addition, we can also provide the overall solution from design, construction to production and operation for different customer pain points.
