In the laboratory, SiCl 4 can be prepared by treating silicon with chlorine at 600 °C (1,112 °F): [1] Si + 2 Cl 2 → SiCl 4. It was first prepared by Jöns Jakob Berzelius in 1823. [4] Brine can be contaminated with silica when the production of chlorine is a byproduct of a metal refining process from metal chloride ore.
2 ((CH 3) 3 SiCl + H 2 O → [(CH 3) 3 Si] 2 O + 2 HCl. The analogous reaction of dimethyldichlorosilane gives siloxane polymers or rings: n (CH 3) 2 SiCl 2 + n H 2 O → [(CH 3) 2 SiO] n + 2n HCl. Many compounds containing Si-Cl bonds can be converted to hydrides using lithium aluminium hydride, This kind of conversion was demonstrated for the ...
In the United States Navy, Refueling and Overhaul (ROH) refers to a lengthy refitting process or procedure performed on nuclear-powered naval ships, which involves replacement of expended nuclear fuel with new fuel and a general maintenance fix-up, renovation, and often modernization of the entire ship. In theory, such process could simply ...
Via hydrosilylation, trichlorosilane is a precursor to other useful organosilicon compounds: . RCH=CH 2 + HSiCl 3 → RCH 2 CH 2 SiCl 3. Some useful products of this or similar reactions include octadecyltrichlorosilane (OTS), perfluoroctyltrichlorosilane (PFOTCS), and perfluorodecyltrichlorosilane (FDTS).
2 SiHCl 3 → SiH 2 Cl 2 + SiCl 4; 2 SiH 2 Cl 2 → SiHCl 3 + SiH 3 Cl; 2 SiH 3 Cl → SiH 4 + SiH 2 Cl 2; The silane produced by this route can be thermally decomposed to produce high-purity silicon and hydrogen in a single pass. Still other industrial routes to silane involve reduction of silicon tetrafluoride (SiF 4) with sodium hydride (NaH ...
[4] 4 Si 2 Cl 6 → 3 SiCl 4 + Si 5 Cl 12. This conversion is useful in making silicon-based components of use in semiconducting devices including photovoltaic cells. [1] The compound is also useful reagent for the deoxygenation reactions, such as this general process involving a phosphine oxide: 2 Si 2 Cl 6 + OPR 3 → OSi 2 Cl 6 + PR 3

4) contain pyramidal tricoordinate silicon in the Si 4− 4 anion, isoelectronic with white phosphorus, P 4. [2] [3] Metal-rich silicides tend to have isolated silicon atoms (e.g. Cu 5 Si); with increasing silicon content, catenation increases, resulting in isolated clusters of two (e.g. U 3 Si 2) or four silicon atoms (e.g. [K +] 4 [Si 4] 4−
