What is Tetrachlorosilane?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is it which has developed particularly rapidly in recent years. Do you know about it?
The official answer:Density 1.48 at room temperature and pressure, melting point -70°C, boiling point 57.6°C, the boiling point increases with increasing pressure. Hydrolyses in moist air to silicic acid and hydrogen chloride. Hydrolysis is violent in contact with water and can also react violently with alcohol.
What’s the application of Tetrachlorosilane?
Widely used in the manufacture of silicone compounds such as silicate esters, silicone oils, high-temperature insulating paints, silicone resins, silicone rubber, and heat resistant matting materials. High purity silicon tetrachloride is used for the manufacture of polysilicon, high purity silicon dioxide and inorganic silicon compounds, quartz fibers. The military industry is used to manufacture smoke screen agents. The metallurgical industry is used to manufacture corrosion-resistant ferrosilicon. The foundry industry uses it as a mold release agent. It is an essential chemical raw material for large industrial production.
