Physicochemical model as a method for calculating and making consistent thermodynamic properties of structural units in alkali silicate melts

The physicochemical modeling of formation of alkali silicate melts in the temperature range 298.15–1473 K has been performed. Correction of the results of calculations based on spectroscopic data has been performed to make consistent the thermodynamic properties of lithium, sodium, and potassium silicates and calculate the thermodynamic properties of structural units Q n , which exist in alkali silicate melts.
