摘要：

Mechanochemical activation followed by annealing at moderate temperatures results in the stabilisation at room temperature of the high ionic conductor oxide gamma-Bi(2)VO(5.5) belonging to the Bi-V(V)-O(2) system, while in the Bi-V(IV)-O(2) system a non-previously reported fluorite-type f-Bi(2)VO(5) phase is isolated. All alpha-, beta- and gamma-Bi(2)VO(5.5) and f-, alpha- and beta-Bi(2)VO(5), as well as amorphous powders with 2Bi(2)O(3):V(2)O(5) and Bi(2)O(3):VO(2) compositions, are studied by X-ray powder diffraction at ambient and high temperatures, thermal analysis and scanning electron microscopy.
