This paper reports on a thermodynamic evaluation of the ZrO{sub 2}-MgO system that has been developed and combined with previous assessments of the ZrO{sub 2}-YO{sub 1.5} and YO{sub 1.5}-MgO systems to describe the ZrO{sub 2}-YO{sub 1.5}-MgO system by means of Bonnier's equation. The calculated results are shown by isothermal and vertical sections, a projection of the liquidus surfaces, and the reaction scheme. Comparisons between calculated and experimental diagrams demonstrate that the calculations satisfactorily account for most of the available experimental data.
