摘要：

The crystal structure of compositionally homogeneous, nanocrystalline ZrO2-12 mol% Y2O3 powders was studied by X-ray diffraction. By applying the Rietveld method, it was found that these powders present a tetragonal phase with an axial ratio of unity, but with the oxygen ions displaced from their ideal fluorite positions along the c-axis (t "-form of the tetragonal phase). The influence of the crystallite size on the oxygen ion displacement was also studied. (C) 1999 Elsevier Science B.V. All rights reserved.
