Estimating Free Energies of Formation of Titanate () and Zirconate () Pyrochlore Phases of Trivalent Lanthanides and Actinides
Figure 4
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 titanate pyrochlore () family. The relationship is estimated as. Standard molar entropies of the oxides and that of aqueous cations are from [32, 33], respectively.
