摘要：

Thermodynamic assessments of the ZrO2-YO1.5 and YO1.5-CaO systems have been conducted and combined with the previous evaluation of the ZrO2-CaO system to describe the ZrO2-YO1.5-CaO system by means of Bonnier's equation. The binary and ternary solution phases are described by a simple substitutional solution model. All binary compounds arc modeled as stoichiometric compounds. Comparisons between calculated isothermal phase diagrams and available experimental data demonstrate that the calculations satisfactorily account for reliable experimental data and no ternary interaction parameter is necessary for the description of the ZrO2-YO1.5-CaO system. The need for a better knowledge of the CaZrO3-YO1.5 system is stressed.
