Silicon tetrachloride or tetrachlorosilane is the inorganic compound with the formula SiCl 4. It is a colorless volatile liquid that fumes in air. It is used to produce high purity silicon and silica for commercial applications.
In inorganic chemistry, chlorosilanes are a group of reactive, chlorine-containing chemical compounds, related to silane (SiH 4) and used in many chemical processes. Each such chemical has at least one silicon-chlorine (Si−Cl) bond. Trichlorosilane is produced on the largest scale. The parent chlorosilane is silicon tetrachloride (SiCl 4). [1]
Carbon tetrachloride was widely used as a dry cleaning solvent, as a refrigerant, and in lava lamps. [42] In the last case, carbon tetrachloride is a key ingredient that adds weight to the otherwise buoyant wax. One speciality use of carbon tetrachloride was in stamp collecting, to reveal watermarks on postage stamps without damaging them. A ...
The rate of consumption of silicon tetrachloride is increasing due to rising demand for polysilicon around the world. Market Overview. Silicon Tetrachloride (SiClâ‚„) is a versatile chemical compound primarily used in the production of high-purity silica and optical fibers. Its applications span various high-tech industries, including ...
Purified trichlorosilane is the principal precursor to ultrapure silicon in the semiconductor industry. In water, it rapidly decomposes to produce a siloxane 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. [2]
The first organosilicon compounds were reported in 1863 by Charles Friedel and James Crafts who synthesized tetraethylsilane from diethylzinc and silicon tetrachloride. [1] However, major progress in organosilicon chemistry did not occur until Frederick Kipping and his students began experimenting with diorganodichlorosilanes ( R 2 SiCl 2 ...
New research finds a link between eating out of plastic takeout containers and heart disease. The study adds to growing evidence that plastic chemicals may negatively influence your health.
An alternative industrial process for the preparation of very high-purity silane, suitable for use in the production of semiconductor-grade silicon, starts with metallurgical-grade silicon, hydrogen, and silicon tetrachloride and involves a complex series of redistribution reactions (producing byproducts that are recycled in the process) and ...
