Abstract

Layered transition-metal-doped bismuth vanadates, commonly known as BIMEVOX oxides, have very attractive oxygen-ion conductivity properties at moderate temperatures and show promise in applications as electrode materials and membranes for oxygen separation. Of great interest is the relationship between the atomic structure of BIMEVOX materials and their useful physical properties. We are investigating this relationship in order to better understand which structural features produce the best ionic conductors. This research requires the preparation of pure powder and single-crystal samples. Here, we present a novel sol-gel synthesis procedure that reduces preparation time, reduces impurities and yields superior single-crystal samples.
