Effect of Mixture Composition on the Electrophysical Parameters and Emission Spectra of $\mathrm{HCl}$–$\mathrm{O}_2$ and $\mathrm{HCl}$–$\mathrm{Ar}$ Plasma

The effect of the composition of a mixture on the electrophysical parameters and emission spectra of $\mathrm{HCl}$–$\mathrm{O}_2$ and $\mathrm{HCl}$–$\mathrm{Ar}$ plasma was analyzed. Data on the gas temperature and reduced electric-field intensity are obtained. Based on an analysis of the emission spectra of plasma, the dilution of $\mathrm{HCl}$ with argon and oxygen is shown to result in the disproportionation of concentrations of $\mathrm{Cl}$ and $\mathrm{H}$ atoms due to the occurrence of secondary atomic and molecular processes.
