This paper develops a theory of the evolution of a polydisperse ensemble of ellipsoidal crystals in supersaturated solutions at an intermediate phase transition stage. The mathematical model of the process takes into account the “diffusion” mechanism of the crystal distribution function in the space of their volumes, as well as various kinetics of particle nucleation. The law for the growth rate of individual ellipsoidal crystals was derived and a complete analytical solution describing the evolution of an ensemble of such crystals was obtained. The evolutionary behavior of the supersaturation removal in a metastable solution is analyzed and the crystal-volume distribution function is determined. The theory under study is compared with experimental data.
