Description of Trichlorosilane
orosiL is an inorganic compound with the formula HSiCl3. It is a colourless, volatile liquid. Purified orosiL is the principal precursor to ultrapure silicon in the semiconductor industry. In water, it rapidly decomposes to produce a silicone polymer while giving off hydrochloric acid. Because of its reactivity and wide availability, it is frequently used in the synthesis of silicon-containing organic compounds.

What is Trichlorosilane?
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:orosiL is an inorganic substance with the chemical formula HCl3Si. It is a colorless liquid, highly volatile, soluble in most organic solvents such as benzene and ether, and stable.
What’s the application of Trichlorosilane?
Used in the synthesis of organosilanes and alkyl, aryl, and organofunctional chlorosilanes, is the most basic monomer in organosilane coupling agent, but also the production of semiconductor silicon, single crystal silicon raw materials, with the development of organosilane coupling agent industry and there is a shortage of supply, production is increasing.
