Estimating Free Energies of Formation of Titanate () and Zirconate () Pyrochlore Phases of Trivalent Lanthanides and Actinides
Figure 3
A relationship for entropy of formation from oxides () in J/mol K and the empirical oxygen affinity parameter (in J/mol K shown for the zirconate pyrochlore () family. The relationship is estimated as . Standard molar entropies of the oxides and those of aqueous cations are from [32, 33], respectively.
