Abstract:

Halogen-substituted barium indate Ba2In2O5 based brownmillerites Ba1.95In2O4.9F0.1 and Ba1.95In2O4.9Cl0.1 have been synthesized. It has been verified radiographically that the single-phase condition is satisfied. The effect of the substituent ion nature on parameters of the crystalline lattice and lengths of In-O bonds has been revealed. The propensity of the phases under study for hydration and formation of energetically unequal DDe(-) groups in the structure has been proved. In both the cases of doping, the degree of hydration decreased as compared to barium indate Ba2In2O5, which is caused by the participation of the halide ion in the tetrahedral site of indium.
