Abstract

Hollitt's model for prediction of thermodynamic properties in multicomponent silicate melts has been revised to better reflect network modifier depolymerization effectiveness as a function of basicity and melt composition. This model is based on the free energy changes in a melt caused by the breaking of silicate polyions by the addition of basic oxides; these free energy changes are in turn related to the change in the concentration of various oxyanion molarities caused by such additions. Application of the revised model to actual systems shows good agreement with experimental data; possible model improvements are discussed.
