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.
