摘要
Following previous reviews of research results on oxygen ion-conducting materials obtained in the former USSR, this article addresses the case of Bi2O3-based compositions, Phase formation in oxide systems with Bi2O3 thermal expansion, stability. bulk transport properties and oxygen exchange of bismuth oxide solid electrolytes are briefly discussed, Primary attention is focused on oxides with high ionic and mixed conductivity, including stabilized fluorite-type (delta) and sillenite (gamma) phases of Bi2O3, gamma -Bi4V2O11 and other compounds of the aurivillius series. Another major point being addressed is an the applicability of these materials in high-temperature electrochemical cells, which is limited by numerous specific disadvantages of Bi2O3-based ceramics. The electrochemical properties of various electrode systems with bismuth oxide electrolytes are also briefly analyzed.
