Synthesis and Electrolytic Properties of Phases Based on Calcium Thiogadolinate as a Function of Method of the Precursor Synthesis

Abstract

Differently treated phases based on CaGd 2 S 4 are studied by electrochemical methods. The range of solid solutions, electrolytic temperature interval, and averaged transport numbers for ions and electrons are determined. Compositions with best electrolytic properties are established. The origin of conduction in a CaGd 2 S 4 -based solid electrolyte is investigated. The obtained data show the phases to be sulfide-conducting solid electrolytes with a small share of cationic conduction.
