Abstract

The electrode resistances of solid solutions of 75 mol% Bi2O3−25 mol% Er2O3 with sputtered and with copressed gold gauze electrodes were compared. In contrast with literature no enhancement of the electrode process could be observed for the copressed electrodes. The measurements show an oxygen partial pressure dependence of power−0.5 for the electrode resistance. Additionally 18O2 exchange results also point to a low oxygen coverage and dissociative adsorption of oxygen. The electrode surface contributes significantly to the electrode process.
