Получен новый хлорзамещенный браунмиллерит Ba195In2O4.9Q0.1, изучены его структура, термические и электрические свойства. Установлено, что введение хлорид-иона обусловливает смену типа проводимости со смешанного ионно-дырочного на кислородно-ионный. Показано, что гетеровалентное допирование (F-, Cl-) перовскитоподобной матрицы приводит к повышению химической стабильности в СО2-содержащей атмосфере.

The novel brownmillerite-type Cl-contained compound Ba195In2O4.9Cl0.1 was synthesized, and its structure, hydration processes, electrical properties were investigated. It was found that the Cl-doping of oxygen sublattice in Ba2In2O5 led to the replacement of the mixed ionic-hole conductivity to oxygen-ionic conductivity. The anionic heterovalent doping (F-, Cl-) of perovskite-related matrix led to the improvement of chemical stability against CO2 and wet vapor.
