Abstract

Our earlier structural model for binary silicate melts and glasses is extended. More general expressions for the enthalpy and nonconfigurational entropy are given. Expressions for partial thermodynamic properties are derived. A least-squares optimization program permits all available thermodynamic and phase diagram data to be optimized simultaneously within experimental error limits. The model is extended from MO-SiO₂ to M₂O-SiO₂ solutions. Data in acidic melts is well represented for the Na₂O-SiO₂ system. Examples of optimizations for the MnO-SiO₂, CaO-SiO₂, and Na₂O-SiO₂ systems are presented. The model is extended to include sulfide ion. Good predictions of sulfide capacities are obtained.
