Abstract [en]

An optimized set of thermodynamic functions for the K2O-SiO2 system at 10(5) Pa pressure was obtained by considering available phase diagram and thermodynamic data. KSi0.25O and SiO2 were selected as components for the liquid phase. With respect to these components, the highly non-ideal interactions of potassium oxide and silica could be described by using only three temperature-independent Redlich-Kister coefficients for the excess G of the liquid phase. The result is in good agreement with experimental data.
