Abstrakt: Nanopowders of tysonite solid solutions La1 − xBaxF3 − x (х = 0–0.07) are synthesized for the first time through the thermal decomposition of lanthanum and barium trifluoroacetates. Samples are characterized via electron microscopy, X-ray phase analysis, and impedance spectroscopy. Nanoparticles are found to be crystalline and have characteristic sizes of 20–75 nm. The ionic conductivity of solid solutions up to 300°C is determined by surface phenomena at the particle boundaries. [ABSTRACT FROM AUTHOR]
