The paper shows the possibility of self-organization of microparticles of impurity nickel atoms in silicon under certain thermodynamic conditions. It was found that the concentration of microparticles in the volume is distributed almost uniformly. It was found that upon additional annealing, self-ordering of microparticles of impurity atoms in the silicon bulk and the formation of Schottky micro-barriers occur. The study of the I – V characteristics of these samples showed that at the points where the microscopy of nickel atoms formed, it has a diode character. The obtained experimental data show the possibility of creating photocells (PV) based on compensated silicon by the impurity of nickel atoms. To study the fundamental electrophysical parameters of photocells, modern methods and instruments were used, such as an MIC-5 infrared analysis microscope, Oxford Instruments ZEISS EVOMA 10 REM analysis, XIA-200 atomic force microscope, and X'PertPowder diffractometer. Micro- and nanoclusters found in silicon are explained by the accumulation of concentration of nickel atom clusters. It has been established that the overgrown clusters of impurity nickel atoms lead to an improvement in the electrophysical parameters of photocells.

The solubility of the components in the system {84,3%Σ[Ca(ClO3)2+ Mg(ClO3)2]+15,7%Σ[CaCl2+MgCl2]}-CH3COOH·NH2C2H4OH - H2O was studied by visually polythermal method. The system was studied using six internal sections, on the basis of which a polythermal solubility diagram of the system was constructed. The surface of the liquidus of the polythermal solubility diagram of the system is divided into the crystallization fields of ice, [Ca(ClO3)2·Mg(ClO3)2], [CaCl2·MgCl2], CH3COOH, CH3COOH·NH2C2H4OH and a new compound of the composition CaOHClO3·2NH2C2H4OH·2H2O. The above fields in the solubility diagram converge at four nodal non-invariant points. The compound was precipitated in the crystalline from the assumed area of its crystallization and identified by chemical, x-ray phase and thermogravimetric analysis methods. It was found that the largest volume in the solubility diagram belongs to the crystallization field CaOHClO3·2NH2C2H4OH∙2H2O due to its low solubility in comparison with other components of the system. Analysis of the radiograph of the initial components and the synthesized complex based on them shows that diffraction reflexes differ from each other, both in the value of interplanar distances and in the intensity of diffraction lines. Thermal analysis also confirms the identity of the new compound. The obtained data on the solubility of components in the studied system can serve as a scientific basis for obtaining a new complex active preparation based on calcium-magnesium chlorate defoliant and monoethanolammonium acetate.
