Rf plasma processing of silica Semantic Scholar

The processing of silica in an rf plasma was studied with a new experimental system, the process being carried out entirely in the vapor phase. SiO and Si were obtained by either thermal decomposition of SiO2 or reduction by H2. No other reducing material (which, like C, may become a contaminant) was used. The products were collected along the reactor length and analyzed afterward.
