| Abstract: | It is found for hydrated solid solutions of Ba2?0.5x In2O5?x F x · nH2O, Ba2In2O5?0.5y F y · nH2O (0 ≤ x ≤ 0.30; 0 ≤ y ≤ 0.24) that increasing the concentration of fluorine lowers the degree of hydration. The composition of proton-containing groups and the places of their localization in the structure of hydrated oxyfluorides are determined. The presence of fluorine in the complex oxide’s structure helps increase the mobility of protons. |
