Abstract

Ca12Al14O33 is a high temperature oxide ion conductor, as shown by emf measurements between 480 and 1200°C on gas concentration cells containing oxygen gas at different partial pressures, both with and without the presence of water vapour. By attention to the sintering conditions, grain boundary impedances can be reduced in magnitude until they are comparable to bulk crystal impedances. The oxide ion conductivity is 10-6 ohm-1 cm-1 at 300°C, rising to 10-2 ohm-1 cm-1 at 1200°C, with an activation energy of 0.81eV. These conductivity values are 8-10 times lower than those of the most conducting yttria-stabilised zirconias.
