摘要：
A thermodynamic model of silicate melts based on the theory of associated solutions is developed. The model presumes the formation of silicon-oxygen groups of arbitrary sizes and spatial configurations. The model approximates the concentration and temperature dependences of the thermodynamic properties of K2O-SiO2 melts with an accuracy not worse than that of experimental data and correctly describes phase equilibria in this system. The thermodynamic characteristics of self-polymerization of silica are found to be independent of the type of silicate melts.
