Abstract

A review is made of the physicochemical factors causing the variability of the properties of inorganic solid phases having the same stoichiometry of the elemental composition, but different actual structures. These factors lead to spatial inhomogeneity in the composition and structure of the solid phases and determine the time profile of the stoichiograms and kinetic dependences for the dissolution of these substances in the dynamic differential dissolution (DD) mode. A discussion is given of the results obtained by mathematical simulation of dynamic dissolution of solid phase mixtures, which show how the selectivity and efficiency of the separation of the phase mixtures depends on their dispersion ability. Various aspects are considered of the use of the DD method for detecting spatial inhomogeneity manifestations in the composition and structure of solids and materials.
