Development of a Quasi-chemical Viscosity Model for Fully Liquid Slags in the Al₂O₃–CaO–‘FeO’–MgO–SiO₂ System. Part 3. Summary of the Model Predictions for the Al₂O₃–CaO–MgO–SiO₂ System and Its Sub-systems

Abstract

A structurally-based quasi-chemical viscosity model for fully liquid slags in the Al₂O₃–CaO–‘FeO’–MgO–SiO₂ system has been developed. The focus of the work described in the present paper is the analysis of the experimental data and viscosity models in the quaternary system Al₂O₃–CaO–MgO–SiO₂ and its sub-systems.
A review of the experimental data, viscometry methods used and viscosity models available in the Al₂O₃–CaO–MgO–SiO₂ and its sub-systems is reported. The quasi-chemical viscosity model is shown to provide good agreement between experimental data and predictions over the whole compositional range.
