Dichlorosilane reaction with water
Web4) and water vapor as the reactants and ammonia as a catalyst. They found that they could deposit SiO 2 thin films at room temperature with the help of a catalyst to provide the energy necessary to overcome the reaction energy. Eleven years earlier, Chapple-Sokol and Gordon [3] experimented with depositing SiO 2 with dichlorosilane (SiCl 2H 2 ... WebDICHLOROSILANE. Product Code: SID3368.0 . CAS No: 4109-96-0 . ... These reagents and their reaction by-products are safer and more easily handled and disposed than many other reducing agents. The metallic nature of silicon and its low electronegativity relative to hydrogen lead to polarization of the Si-H bond yielding a hydridic hydrogen and a ...
