Abstract

Functional materials with high ionic conductivity based on bismuth trifluoride. A.B. SLOBODYUK, M.M. POLYANTSEV, V.K. GONCHARUK, V.Ya. KAVUN (Institute of Chemistry, FEB RAS, Vladivostok).

Studies of ionic mobility and electrophysical properties of solid solutions with fluorite structure formed in ternary systems containing BiF3 were analyzed and summarized. Cases of the cell parameter concentration dependence deviations of some solid solutions from the Vegard’s law were studied and the reasons of the deviations were suggested. The synthesized solid solutions possess high ionic conductivity of ~10–3–10–2 S/cm in temperature range 400–550 K that allows to consider them as prospective functionalized materials.
