Abstract

Mechanochemical activation followed by annealing at moderate temperatures results in the stabilisation at room temperature of the high ionic conductor oxide γ-Bi2VO5.5 belonging to the Bi–VV–O2 system, while in the Bi–VIV–O2 system a non-previously reported fluorite-type f-Bi2VO5 phase is isolated. All α-, β- and γ-Bi2VO5.5 and f-, α- and β-Bi2VO5, as well as amorphous powders with 2Bi2O3∶V2O5 and Bi2O3∶VO2 compositions, are studied by X-ray powder diffraction at ambient and high temperatures, thermal analysis and scanning electron microscopy.
