A nanocrystalline ZrO2–10 mol% Y2O3 powder synthesized by a nitrate–citrate gel-combustion process and stabilized in the metastable t′′-form of the tetragonal phase has been characterized using mainly the Perturbed Angular Correlations technique. The determined hyperfine interaction allows a clear distinction between the zirconium surroundings in the t′′-form and those already known of the other forms of the tetragonal phase. Oxygen vacancies movement is revealed as a slow diffusion involving a very small activation energy. As the powder is heated, a transformation is observed to occur around 560°C, which is consistent with a t′′-to-cubic transition.
