Abstract

Electrical conduction in sintered oxides of the system Bi2O3-Tb2O3.5 has been investigated. Oxide ion conduction was observed in the rhombohedral (low temperature) phase and the f c c (high temperature) phase present in the composition range less than 20mol% Tb2O3.5. The fcc phase could be stabilized at lower temperatures by adding more than 30 mol % Tb2O3.5. In addition to oxide ion conduction, appreciable electronic conduction appeared in this composition range. The oxide ion transport number of this phase decreased with increasing content of Tb2O3.5 and the specimens having 40–50 mol % Tb2O3.5 showed mixed conduction where electrical conduction was comparably contributed by oxide ions and electrons. Electronic conduction in the fee phase was considered to be due to the change in valence of terbium at high temperatures.
