Gladkov, E. Medvedev] The nucleation and growth of crystals in a gel of alkali lead borosilicate composition are investigated. It is revealed that dendrites are formed on the surface of the gel and that needle-shaped crystals grow in the gel bulk. An analysis of the distribution of crystals in the gel allows the assumption that the mechanism of their formation is identical to the fluctuation nucleation of the solid phase. The crystal nuclei play the role of attracting sets or attractors for the other particles of the crystallizing compound, which, in small portions, move toward nuclei. The process is governed by the moisture content, the viscosity, and the structure of the gel. A mathematical model of crystallization is proposed. Pleiades Publishing, Inc., 2006 Gladkov S.
