Abstract

The impedance of a sodium β-alumina based electrochemical sensor, developed for the determination of the lithium activity in liquid metal blends, was investigated as a function of temperature. The impedance spectra could be rationalised in terms of purely resistive bulk conduction, dispersive grain boundary conduction and a diffusion-limited electrode conduction. Values of log (T/ R), as derived from the interior grain and grain boundary resistivities were found to follow an Arrhenius behaviour. Corresponding activation energies of respectively 30 and 58 kcal/mol were calculated.
