Abstract

The phase diagram of the system was reinvestigated using hydrothermal techniques. Cubic, tetragonal and monoclinic ZrO2 solid solutions are present. The tetragonal solid solution decomposes to monoclinic and cubic solid solutions by a eutectoid reaction at 1050 + or - 50oC. The solubility limits of the tetragonal and cubic solid solutions are approx 18 and 70 mol.% CeO2 respectively at 1400oC, and approx 16 and 80 mol.% CeO2 at 1200oC. Solubility limits of the monoclinic and cubic solid solutions are approx 1.5 and 88 mol.% CeO2 at 1000oC, and 1.5 and 98 mol.% CeO2 at 800oC, respectively. The compound Ce2Zr3O10 is not found.-D.T.
