ABSTRACT:
Disclosed is a stable bismuth oxide composition having excellent oxygen ion conductivity comprising: from 50 to 90 mole % Bi.sub.2 O.sub.3, from 10 to 40 mole % of a rare earth oxide, such as yttria; and from 0.1 to 10 mole % g an oxide compound, such as ZrO.sub.2 or ThO.sub.2. The composition retains its oxygen ion transport capabilities even after prolonged annealing.
