Thermodynamic characteristics of ternary sulfides MLn₂S₄ and solid solutions thereof
Thermodynamic characteristics of ternary sulfides MLn₂S₄ and soiid solutions thereof have been determined by EMF method in various modifications. The research results have shown that solid electrolytes CaGd₂S4 and BaTm₂S4 are stable compounds within the electrolytic range 653-723 K. The simultaneous...

The research results have shown that solid electrolytes CaGd₂S4 and BaTm₂S4 are stable compounds within the electrolytic range 653-723 K. The simultaneous determination of the binary sulfide activity in ternary BaTm₂S₄, CaY₂S₄, CaSm₂S₄, CaPr₂S₄ systems and of the cation and anion transfer numbers allowed us to estimate the phase stability limits and to propose a vacancy mechanism of defect formation and suggest the predominantly sulfide-ion type conductivity in the solid electrolytes studied. |
