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.
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 ...
The pyrolysis of SiBr 4 does have the advantage of depositing silicon at faster rates than that of SiCl 4, however SiCl 4 is usually preferred due to its availability in high purity. [13] Pyrolysis of SiBr 4 followed by treatment with ammonia yields silicon nitride (Si 3 N 4 ) coatings, a hard compound used for ceramics, sealants, and the ...
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 ...
4-x SiCl x. These chlorides are produced by the "Direct process", which entails the reaction of methyl chloride with a silicon-copper alloy. The main and most sought-after product is dimethyldichlorosilane: 2 CH 3 Cl + Si → (CH 3) 2 SiCl 2. A variety of other products are obtained, including trimethylsilyl chloride and methyltrichlorosilane ...
Nanowires based on silicon and manganese can be synthesised from Mn(CO) 5 SiCl 3 forming nanowires based on Mn 19 Si 33. [ 14 ] or grown on a silicon surface [ 15 ] [ 16 ] [ 17 ] MnSi 1.73 was investigated as thermoelectric material [ 18 ] and as an optoelectronic thin film. [ 19 ]
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 ...
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).
