The short-range order of ZrO2-3 mol% Y2O3 powders is studied by EXAFS spectroscopy in relation to the powder preparation process. For powders prepared by both ball milling and coprecipitation, the Fourier transforms of the Y3+ and Zr4+ K-EXAFS spectra are analyzed. For both preparation processes, the stabilizing Y3+ ions predominantly substitute Zr4+ ions in the tetragonal ZrO2 modification. Clusters with Y2O3 short-range order were not detected in this study.
