Abstract

A microwave-assisted method for the preparation of substituted bismuth vanadates has been described. The method consists of starting with the respective oxides mixed in stoichiometric proportions and exposing the mixture to microwaves. Substitution takes place at the vanadium sites and it has been possible to prepare Ag+-, Mn4+-, Ga3+-, Y3+-, and Ce4+-substituted compounds with up to 10% substitution. Mn4+- and Ag+-substituted compounds are found to exhibit better oxygen ion conductivities than any reported so far in the literature.
