Abstrakt:	Chlorine-substituted brownmillerite BaInOC was obtained from barium indate BaInO by solid-phase synthesis. The ability to absorb water from the gas phase was confirmed by thermogravimetric studies. The transport properties were studied while varying the thermodynamic parameters of the external environment ( T, pO, pHO). The chloride ions in the oxygen sublattice of barium indate BaInO were found to affect the ion conductivity. In a humid atmosphere, the sample exhibited proton conductivity ( E = 0.54 eV), whose contribution became dominant below 300°C. [ABSTRACT FROM AUTHOR]
