The atomic-scale structure of nanocrystalline ZrO{sub 2} obtained by ball milling has been studied using high-energy x-ray diffraction and the atomic pair distribution function technique. The studies show that, upon relatively short milling times, the parent crystalline material, monoclinic ZrO{sub 2}, evolves into a nanocrystalline phase that is locally similar to monoclinic zirconia but shows a cubic-type ordering at nanometer-range distances. The result underlines the importance of local structural distortions in stabilizing the technologically important cubic zirconia at room temperature.
