摘要

The CaYb2S4 compound and the phases based on it are fabricated. The ranges of solid solutions of CaS and Yb2S3 in calcium thioytterbiate are determined using the methods of x-ray diffraction analysis and conductometry. Average ionic, electronic, cationic, and anionic transport numbers and the coefficients of self-diffusion and diffusion of majority carrier in the Yb2S3 solid solution based on CaYb2S4 are determined by the modified emf method, the polarization Hebb-Wagner method, and potentiostatic chronoammetry. To discuss the mechanism of ionic transfer, the data on the pycnometric and X-ray densities are compared.
