Abstract
Atomic resonance absorption spectroscopy coupled with a shock tube is a powerful technique for studying high temperature dynamics of reactive systems. Presently, high temperature pyrolysis of SiCl_4–Ar mixtures has been studied behind reflected shock waves. Using time-resolved absorption profiles at 121.6 nm and a detailed reaction model, the absorption cross sections of SiCl_4, SiCl_3, SiCl_2 and Cl have been measured. Results agree well with available data for SiCl_4 and constitute, to our knowledge, the first measurements for SiCl_3, SiCl_2 and Cl at the Lyman-α wavelength. These data are relevant to silica particle production from SiCl_4-oxidant mixtures combustion synthesis.
