Abstract:	Coefficients of self-diffusion and coefficients of diffusion of the sulfur ion in solid electrolytes BaSm₂S₄ and CaGd₂S₄ are determined with recourse to methods of conductimetry and potentiostatic chronoamperometry. A vacancy mechanism for the defect formation in solid solutions on the basis of barium thiosamarate and calcium thiogadolynate is proposed.

Keywords:	stoichiometric compound solid electrolyte transport numbers ionic conduction diffusion coefficient self-diffusion coefficient
