The Local Structure and Hydration Processes of Halogen-Substituted Perovskites Based on Ba4In2Zr2O11

Halogen-substituted perovskites Ba 4 In 2 Zr 2 O 10.95 F 0.1 and Ba 4 In 2 Zr 2 O 10.95 Cl 0.1 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 fou...

Summary:Halogen-substituted perovskites Ba 4 In 2 Zr 2 O 10.95 F 0.1 and Ba 4 In 2 Zr 2 O 10.95 Cl 0.1 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.
