A study of the thermodynamic properties of MgO-SiO2 system

Thermodynamic assessment of LiCl–NdCl3 and LiCl–PrCl3 quasi-binary systems

“…(4), E G m is the excess Gibbs energy of liquid phase. With the assumption [55,56] that the same interaction exists between the neutral and anionic species, counted per negative charge, the number of independent interaction parameters could be remarkably reduced. However, an additional interaction parameter between Cl − and LnCl 6 −3 (Ln = Nd, Pr) was found necessary to avoid unrealistic immiscibility in the region between LiCl and "Li 3 LnCl 6 " (Ln = Nd, Pr), the notation means that there is no compound of the type Li 3 LnCl 6 with NdCl 3 and PrCl 3 .…”

Thermodynamic assessment of B2O3–MgO binary system

“…As the two-sublattice model for ionic solutions developed by Hillert et al [44], which is based on the Compound Energy Formalism (CEF) in addition to the restriction of electric charge balance that must be always zero, was employed to model the liquid phase of MgO-SiO 2 [45], CaO-SiO 2 [46] [15][16][17]34].…”

Thermodynamic assessment of NdBr3 unary and LiBr–NdBr3 binary system

“…(4), E G m is the excess Gibbs energy of the liquid phase. For the purpose of the thermodynamic optimization, the assumption [29,30] that the same interaction exists between the neutral and anionic species was adopted, and the number of independent interaction parameters was thus remarkably reduced. Therefore, the excess Gibbs energy was written as follows:…”
