The work was aimed at establishing new correlations between some known energetic characteristics of several materials and their performance. A symbolic power dependence between the specific formation enthalpy decrement of some solid materials and the specific energy of their crystal lattice has been found, which enables E(cr.lat) (spec.) to be used as a characteristic function for the prediction and performance optimization process. The correlation between the specific formation enthalpy decrement of solid materials and their specific heat capacity was shown to have a maximum within 0.6–1.0 J/(g·K). This correlation was confirmed experimentally with some epoxide component as an example, which allows prediction by Cp to be performed as well.
