The CaO–Al 2 O 3 –SiO 2 system has been assessed with the CALPHAD technique, based on recent assessments of its binary systems. A new species AlO 2 −1 was introduced for modeling liquid Al 2 O 3 . The ternary liquid phase was described using the ionic two‐sublattice model as. The available experimental data were critically examined, and a self‐consistent set of thermodynamic descriptions was obtained. Various phase diagrams and property diagrams, including isothermal sections, isoactivity lines, and a projection of the liquidus surface, are presented. Information on viscosity seems to support the use of the AlO 2 −1 species.
