Abstract:

(Ba1 - x Ca (x) )(6)Nb2O11 solid solutions were synthesized. The compositions were shown to be single-phase at 0.23 a parts per thousand currency sign x a parts per thousand currency sign 0.47 and have a double perovskite cubic structure with an incomplete oxygen sublattice. The interaction of solid solutions with water vapor and their electrical properties were studied. In dry atmosphere, these complex oxides were mixed oxygen-hole conductors. In humid atmosphere, they intercalated water and exhibited protonic conductivity. The influence of Ba/Ca isovalent substitution, the dynamics of the oxygen sublattice, and the concentration of intercalated water on the value and contribution of protonic and hole conductivity was analyzed.
