Coupled thermodynamic-phase diagram assessment of the rare earth oxide-aluminium oxide binary systems

A critical assessment of the binary R2O3-Al2O3 systems (RLa, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) has been carried out through the technique of coupled thermodynamic-phase diagram analysis. Thermodynamic properties of the various compounds and of the liquid oxide solutions have been deduced and optimized phase diagrams have been calculated.
