The new phase Ba5In2Al2Zr0.9Nb0.1O13.05 with hexagonal perovskite structure was obtained. substitution of Zr4+ by smaller Nb5+ accompanied the incorporation oxygen interstitials and did not lead to a significant change in lattice parameters. It established that investigated sample capable for water from gas phase, hydration degree value 0.24 mol H2O. IR-spectroscopy analysis defined presence OH...
