The model of fixed polidentate centers is extended onto ionic exchange equilibria. Examination of ionic exchange equilibria for combined material proved that it is efficient for separating lithium ions from that of alkaline metals. Formation of regular symmetrical growth figures from random non-symmetrical nuclei in the course of nucleation and growth to impingement processes is described in terms of cellular automata with the account of crystal symmetry of original reagent. An essential peculiar feature of the approach developed is that both formation and subsequent stable growth of a nucleus are described in one and the same terms., whereas within traditional geometric-probabilistic models details of nucleation are beyond considerations.
