Abstract:The possibility of using sulfide-conducting solid electrolytes of the Me S-Ln 2 S 3 ( Me = Ca, Ba; Ln = Y, Nd, Pr, Sm, Tm) systems in sensors for analysis of sulfur-containing media is investigated. The appropriate design parameters and operating conditions of the sensors are chosen. The influence of multicomponent impurities on the sensor selectivity is analyzed.
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.
