Electrical transport properties of beta-bismuth molybdate Bi2Mo2O9

Research output: Contribution to journalArticleAcademicpeer-review

Abstract

Results are given for the electrical conductivity and ionic transport numbers of polycrystalline, sintered ß-Bi2Mo2O9 in the temperature region 300oC to 650oC and at partial oxygen pressures of 1-10-6 bar. The material shows mixed conductivity over the whole temperature and pressure region. The oxygen pressure dependence is explained by an acceptor controlled behaviour, with copper impurities and oxygen vacancies as the dominating defects
