Abstract
The experimental work on the ZrO2-YO1.5-CeO2 system, its limiting quasi-bin aries and previous thermodynamic assessments are reviewed and evaluated. Is othermal sections of ZrO2-YO1.5-CeO2 system in the temperature region betwe en 1450 and 1800 C are estimated according to the substitutional model usin g the Bonnier equation. The CSS + YSS two-phase region of the calculated is othermal section at 1700 degreesC was found to be in good agreement with th e experimentally obtained ternary diagram of Longo and Podda. The phase com position in the ZrO2-rich corner however disagreed significantly.
