Abstract
In this article through joint cationic and anionic doping brawnmillerite Ba2In2O5 compounds obtained from the homogeneity range Ba0.8-0.5хLa1.2In2O5.6-хFx (0 ≤ х ≤ 0.2). It is established that structures are characterized by cubic symmetry (space group Pm3m) by the method of the full-profile analysis of Rietveld. It is proved these phases are capable to high-temperature protonic conductivity. It was found that mixed anion effect comprising the growth of electrical conductivity at low concentrations of fluoride observed for the Ba0.8-0.5хLa1.2In2O5.6-хFx.
