Abstract

Mechanisms of nonequilibrium processes and patterns of physicochemical transformations in solids need to be known to create materials with desired properties. Given that the reactivity of solids is determined by surface activity, kinetic problems can be solved though the relative change in free surface energy. This study aimed to experimentally assess the adequacy of an energy model applied to kinetic description of topochemical reactions. The polarization component of surface tension, determined by the OWRK method, was used as the principal information parameter. The model was tested using a finely dispersed bark-glyoxal composition and a finely dispersed bark-basalt composition. The fine powders were obtained by dry mechanical dispersion in a planetary ball mill. It was proven that the proposed kinetic model allows studying the kinetics and the mechanism of interaction in solid-phase systemsm, and calculating the reaction rate constant.
