Abstract
Nonstoichiometry of sulfides of cadmium and lead is studied by the method of coulometric titration in electrochemical cells with sulfide-conductive solid electrolytes on the basis of MLn2S4. The range of the homogeneity region is estimated at temperatures 300 to 400°C. A feasible model for the formation of defects in nonstoichiometric sulfides of cadmium and lead is proposed.
