Abstract

Comprehensive descriptions of the thermodynamic properties and experimental information in three oxide Systems ZrO2-Y2O3, ZrO2-CeO2 and Y2O3-CeO2 aregiven and thermodynamic models for the calculation of these systems are discussed. The phase diagrams of the quasi-ternary ZrO2-Y2O3-CeO2 system in the zirconia-rich corner are estimated at different temperatures with a substitutional model and Muggianu's extrapolation. The equilibrium phase diagram calculation is extended to low temperatures, as well as the Gibbs free energy of the tetragonal, monoclinic and cubic phases of zirconia doped with yttria and ceria.
