Dimethyldichlorosilane is a tetrahedral organosilicon compound with the formula Si(CH 3) 2 Cl 2. At room temperature it is a colorless liquid that readily reacts with water to form both linear and cyclic Si-O chains. Dimethyldichlorosilane is made on an industrial scale as the principal precursor to dimethylsilicone and polysilane compounds.
Dichlorosilane, or DCS as it is commonly known, is a chemical compound with the formula H 2 SiCl 2. In its major use, it is mixed with ammonia (NH 3) in LPCVD chambers to grow silicon nitride in semiconductor processing. A higher concentration of DCS·NH 3 (i.e. 16:1), usually results in lower stress nitride films.
Consequently, if a liquid has dynamic viscosity of n centiPoise, and its density is not too different from that of water, then its kinematic viscosity is around n centiStokes. For gas, the dynamic viscosity is usually in the range of 10 to 20 microPascal-seconds, or 0.01 to 0.02 centiPoise. The density is usually on the order of 0.5 to 5 kg/m^3.
Methyltrichlorosilane, also known as trichloromethylsilane, is a monomer and organosilicon compound with the formula CH 3 SiCl 3. It is a colorless liquid with a sharp odor similar to that of hydrochloric acid. As methyltrichlorosilane is a reactive compound, it is mainly used a precursor for forming various cross-linked siloxane polymers.
The chemical formula of PDMS is CH 3 [Si(CH 3) 2 O] n Si(CH 3) 3, where n is the number of repeating monomer [Si(CH 3) 2 O] units. [4] Industrial synthesis can begin from dimethyldichlorosilane and water by the following net reaction: n Si(CH 3) 2 Cl 2 + (n+1) H 2 O → HO[Si(CH 3) 2 O] n H + 2n HCl. The polymerization reaction evolves ...

4 (g) + 2 H 2 (g) → Si(s) + 4 HCl (g) at 1250°C [11] The produced polysilicon is used as wafers in large amounts by the photovoltaic industry for conventional solar cells made of crystalline silicon and also by the semiconductor industry. Silicon tetrachloride can also be hydrolysed to fumed silica. High purity silicon tetrachloride is used ...
Silanes with one, two, three, or four Si-H bonds are called hydrosilanes. Silane is again the parent member. Examples: triethylsilane (HSi(C 2 H 5) 3) and triethoxysilane (HSi(OC 2 H 5) 3). Polysilanes are organosilicon compounds with the formula (R 2 Si) n. They feature Si-Si bonds. Attracting more interest are the organic derivatives such as ...
