Gibbs free energy of formation of liquid lanthanide–bismuth alloys

The linear free energy relationship developed by Sverjensky and Molling provides a way to predict Gibbs free energies of liquid Ln–Bi alloys formation from the known thermodynamic properties of aqueous trivalent lanthanides (Ln3(5(6+). The Ln–Bi alloys are divided into two isostructural families named as the LnBi2 (Ln=La, Ce, Pr, Nd and Pm) and LnBi (Ln=Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm and Yb). The calculated Gibbs free energy values are well agreed with experimental data.
