Sulfide ceramic materials based on CaYb2S4 with functional electrolytic properties

Abstract

Phases based on the CaYb 2 S 4 compound with hyperstoichiometric compositions of the CaS and Yb 2 S 3 sulfides are investigated. The region of solid solutions and the electrolytic temperature range are determined, and the average ion, cation, anion, and electron transport numbers are measured. The pycnometric and X-ray densities are compared. A possible mechanism of defect formation is proposed.
