Sulfide Ceramic Materials Based on CaYb2S4 with Functional Electrolytic Properties

摘要

Phases based on the CaYb2S4 compound with hyperstoichiometric compositions of the CaS and Yb2S3 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.
