Abstract

The surface oxygen exchange rate has been measured on thin samples of the solid solutions of bismuth oxide with erbium oxide and with terbium oxide. These materials show high surface oxygen exchange values. For the s.s. of Bi2O3 with 40 mol% Tb2O3 (BT40) a value of 2.5×l0−8 mol.cm−2.sec−1 is found at 973 K. The exchange is thermally activated with E = 110 kJ/mol for BT40, 130 kJ/mol for BE25 and 155 kJ/mol for BE30 (Bi2O3 doped with resp. 25 and 30 mol% Er2O3). The exchange rate follows a √pO2 dependence. Oxygen exchange measurements on BE25 powder indicates that the dissociative adsorption of oxygen is the rate limiting step in the exchange process.
