Thermodynamic optimization of the K2O-Al2O3-SiO2 system
Source abstract
Abstract
Abstract A critical evaluation and thermodynamic optimization of experimental phase diagrams and thermodynamic properties of the K 2 O-Al 2 O 3 -SiO 2 system was performed at 1 bar total pressure. A set of self-consistent thermodynamic functions of all phases in the K 2 O-Al 2 O 3 -SiO 2 system was obtained. The liquid phase was described using the Modified Quasichemical Model with the KAlO 2 associate component. The set of optimized model parameters obtained for all phases reproduces available and reliable thermodynamic properties and phase diagram data as well as the melt structure of the K 2 O-Al 2 O 3 -SiO 2 system within the experimental error limits.
