Abstract

In the present work a method for calculating the standard molar enthalpy and Gibbs free energy of formation anhydrous silicates is proposed.
The method is based on the principles of structural analogy and additivity of properties involving thermodynamics of substances and information
on parameters which are considered insufficiently defined. Testing of the proposed method at thermodynamic evaluation of reactions,
involving anhydrous silicates, has yielded positive results - chemical equilibrium estimation error does not exceed 1-3%.
