Abstract: The following paper contains a model of the mechanism of successive cluster formation and its integration into the grid of quartz crystal with a rearrangement of the electronic structure in the formation of bonds between the embedded complex and the crystal. We considered the questions connected with the formation, self-organization and profiling of quartz crystals under the conditions of non-equilibrium thermodynamics on the example of quartz. Crystallization is carried out by means of thermodynamic and kinetic factors. The first of them determines the driving force of crystallization, prepares this process, while the second one implements crystal-forming particles in the grid. Both operating factors are interrelated. The internal energy of the system in the crystalline state is lower than in the initial one, however, the process of transition to the crystalline state does not pass spontaneously. To begin with, it is required to first expend some energy, and then crystallization proceeds spontaneously and is accompanied by the release of excess energy in most cases.
