Abstract

Halogen-substituted perovskites Ba4In2Zr2O10.95F0.1 and Ba4In2Zr2O10.95Cl0.1 are synthesized, and their single-phase composition is verified by X-ray diffraction analysis. Their ability of the studied phases to hydrate and form energetically unequal OH– groups is proved. It is found that introduction of halide ions leads to a decrease in the hydration degree with respect to the matrix composition, which is explained by a decrease in the crystal unit cell free volume Processes.
