Abstract

The total electrical conductivity and the electronic conductivity in silver beta alumina have been determined between 23° and 800°C over a wide range of oxygen partial pressure using a-c and d-c techniques. The ionic transference number was found to be very close to unity under all conditions. Comparison of these measurements with tracer diffusion studies shows that the diffusion of silver ions takes place by an interstitialcy mechanism.
