摘要：
The electrical conductivity of an optical fluoride ceramic in the quaternary system BaF2 + ZnF2 + CdF2 + YbF3 has been determined in the temperature range 338-722 K using impedance spectroscopy (5 to 5 x 10(5) Hz). The 500-K ionic conductivity of the ceramic is sigma = 3.3 x 10(-4) S/cm, which corresponds to the electrical characteristics of single crystals of the best conducting nonstoichiometric M1-x R (x) F2 + x (M = Sr, Ba; R = La-Nd; x = 0.3-0.5) fluorite phases. We have observed nonmonotonic variation (breaks) in temperature-dependent sigma, which is due to competing fluoride ion transport processes in different parts of the ceramic sample. The highly conductive state of the BaF2 + ZnF2 + CdF2 + YbF3 fluoride ceramic seems to be due to the formation of structural regions corresponding to a Ba1-x Yb (x) F2 + x solid solution.
