Abstract :
Group discussions centered on four major topics. 1. (1) The importance to solution modeling of realistic extrapolations of Cp pure liquids below their melting points was underlined.2. (2) The use of interpolation models in the dilute solution ranges of multicomponent solutions was discussed. The commonly used Muggianu model is not good in this respect, the Toop model being more physically realistic. The Kohler model may be a good compromise. The more sophisticated coordination cluster theory provides good predictions for dilute solutions of one or more components.3. (3) For solutions exhibiting short-range order, the similarities and differences among the association, one-sublattice quasichemical and two-sublattice liquid models were elucidated. It was shown that the Gibbs energy equations of these models are very similar so that, with only slight modifications, nearly the same model subroutines can be used for all three.4. (4) Models for molten salt and molten oxide solutions were discussed, with emphasis on the Conformai Ionic Solution Theory, the two-sublattice quasichemical model, and the two-sublattice liquid model. The similarities and differences among these models were shown.
