Abstract

Up to 10 atom.% of Li+, Zn2+, Al3+, Ti4+ and Ge4+ readily substitute for vanadium in Bi4V2O11 stabilizing α/γ structures. The γ-phase are good oxygen-ion conductors, the Ti-substituted γ-phase, Bi4V1.8Ti0.2O10.9, being the best ionic conductor among all the substituted bismuth vanadates investigated. It is conjectured that a high ionic potential of the dopant cation facilitates oxygen-ion mobility in the disordered phase of the substituted bismuth vanadate.

    However, the γ’ form is less conductive than the former. Solid solutions derived from Bi4V2O11 by partial substitution of vanadium with a large variety of metal ions of different sizes and valence states, possess a good oxide anion conductivity [3–14]. These materials are known as BIMEVOX where ME is the dopant metal [3].

    The phase stabilization and hence enhancement of ionic conductivity in these materials may be done by doping with iso- or/and aliovalent cations (ME), which can be formulated as Bi4V2-xMexO11-δ [BIMEVOX]. There are many reports available in the literature on the effect of substitution of Vanadium (V5+) by monovalent [5,6], divalent [7–12], trivalent [13–16], tetravalent [17–21] and pentavalent [22–26] cations. In addition to single cation substitution, there are a number of reports on double substitution at V-site in which high ionic conducting phase stabilization and enhancement of conductivity have been reported [20,27–32].

    After heat treatment, it is observed that, the γ-phase gets converted to β-phase in x=0.05 sample. It has orthorhombic structure and refined with space group Amam [21–27], whereas, 0.10≤x≤0.20 heat treated samples could not show any transformation from phase, γ-phase to α or β phase. After heat treatment, the XRD peaks become sharper as compared to the quenched samples.
