Abstract

Relaxation of 181Ta nuclei due to diffusion of oxygen vacancies in cubic zirconia/yttria has been measured by perturbed angular correlation spectroscopy. The activation energy of the vacancy jump rate is found in a temperature range above 750°C and is in reasonable agreement with the activation energy of ionic conduction. Preliminary results of a 111In/111Cd perturbed angular correlation investigation of high-temperature monoclinic and tetragonal zirconia are also reported.
