摘要：
The anionic conductivity parameters are determined for R1 - ySryF3 - y (R = Ce, Pr, Gd), Zr0.88Y0.12O1.94 single crystals and Zr0.88Y0.12O1.94M0.88Y0.12O1.94 (M = Zr, Hf) bicrystals using an ac (5 Hz to 100 kHz) four-electrode method. The obtained conductometric data are compared with the results of studying these crystals using a two-electrode method. It is shown that physical parameters of R1 - ySryF3 - y fluoride crystals with the tysonite (LaF3) structure are stable at heating in air up to the temperatures of 200-300 degrees C, which is important for their practical application.
