New methods for processing the experimental and calculated thermodynamic data have been elaborated and the existing ones have been improved. The developed approaches provide a physically reasonable description of the first-order phase transitions, which makes it possible to compare and correct the values of their thermodynamic properties, as well as to calculate the thermodynamic parameters of unstudied compounds. Regression equations have been proposed for calculating the standard entropy and enthalpy of formation of lithium, sodium, and potassium silicates and borates. The resulting entropy and enthalpy values for 14 alkali metal silicates and 12 alkali metal borates can be used to optimize the technological processes for manufacturing glass, ceramics, and coatings.
