摘要：

The study of the effect of isomorphous isovalent substitution on the fluoride-ion conductivity in La1-xNdxF3 solid solutions was aimed at optimizing the anionic transport in solid electrolytes with the tysonite-type (LaF3) structure. A series of La1-xNdxF3 single crystals with 0.1 ≤ x ≤ 0.9 was grown for the first time by the Bridgman-Stockbarger method in the fluorinating atmosphere. The ionic conductivity was measured at frequencies ranging from 5 to 500 kHz by the method of impedance spectroscopy (with the use of graphite contacts). The conductivity is maximal at the composition La0.37Nd0.63F3.
