Abstract:

A number of fluorine-substituted compounds were synthesized from brownmillerite Ba2In2O5. The homogeneity range of the Ba2 - 0.5x In2O5 - x F (x) solid solution (x a parts per thousand currency sign 0.3) was determined by X-ray diffractometry. The studied phases were found to be able to incorporate water from the gas phase, due to which their orthorhombic structure transforms into tetragonal one. The degree of hydration decreased as the fluorine content in the solid solution increased. As in the case of Ba2In2O5, the energetically nonequivalent hydroxo groups were found to be the main form of oxygen-hydrogen groups.
