Abstract:	A hydrochloric acid solution of hydrogen peroxide was suggested for etching lead sulfide films. The solubility of lead sulfide in relation to the hydrochloric acid concentration in the etching solution was calculated using thermodynamic analysis, taking into account the stability of lead complex species. The kinetics of hydrogen peroxide decomposition in the hydrochloric acid solution was studied, and the formal rate equation of the process was constructed.
