Anionic Conducting Oxide Ceramics: Microstructure - Property Relations of Bicuvox Ceramics.

Abstract

The bismuth vanadate composition, Bi4V2011, is the parent compound for a new family of oxygen ion conductors. The substitution of various metallic ions for vanadium stabilizes the high temperature gamma-phase and leads to a series of compounds which possess the highest oxygen ion conductivities observed for temperatures below 400 deg C. This paper reports the first studies on the processing, densification and transport properties of copper-doped bismuth vanadate ceramics. Phase-pure materials with densities above 95% of theoretical were obtained using standard ceramic processing approaches. Ionic conductivities in the range of 1 x 10(exp -2) S/cm at 400 deg C were observed for a variety of sintered samples.
