Sur l'Utilisation d'une electrode ponctuelle dans les cellules à oxyde electrolyte solide. II. Application a la détermination des tensions d'oxydoreduction des defauts ponctuels dans l'electrolyte
Abstract
A method is described for direct measurement of oxidoreduction potential of point defects dissolved in solid electrolytes. Measurements were carried out with several solid oxide electrolytes based on zirconia ZrO 2 and hafnia HfO 2. Results allowed us to determine more accurately the electrolytic behaviour of these materials and the reactions involved in the electrochemical blackening of zirconia.
