Notes:
A high-pressure sampling mass spectrometer was used to detect the volatile species formed from SiO2 at temperatures between 1200° and 1400°C in a flowing water vapor/oxygen gas mixture at 1 bar total pressure. The primary vapor species identified was Si(OH)4. The fragment ion Si(OH)3+was observed in quantities 3 to 5 times larger than the parent ion Si(OH)4+. The Si(OH)3+ intensity was found to have a small temperature dependence and to increase with the water vapor partial pressure as expected. In addition, SiO(OH)+, believed to be a fragment of SiO(OH)2, was observed. These mass spectral results were compared to the behavior of silicon halides.
