Y2O3 - containing tetragonal ZrO2 polycrystals (Y-TZP) are prepared by wet chemical methods. This results in sinterreactive ceramics with grain sizes down to 0.1µm. The aging behaviour in air and water at high temperatures has been studied by X-ray diffraction. Important factors on aging are Y-concentration, impurity level and grain size. Y-TZP with 6.1 mol% YO1.5 and a grain size of 0.1µm do not show degradation to monoclinic phase even after 5 hours at 450 K in water.
