The known method offers to obtain monocrystals from the listed salts, however it does not allow to obtain monocrystals of large sizes, high purity, decorative forms. since there is no technological mode that allows obtaining large mono-crystals and crystal aggregates of highly decorative forms. Moreover, the method and speed of cooling the solutions in the solution-glass-water system have a significant impact on the format and quality of the grown single crystals, which, if not cooled correctly, leads to a massive precipitation of the substance on the stack. crystallization. However, as stated, the concentration of the fasting substance in the paste is at its core the same. But if a temperature difference is created in the solution, a gradient of chemical potential will arise in it, which will contribute to the emergence of diffusion and the transfer of concentrations, and hence, towards the growth of crystals. It is known that before this, the introduction of the crystal carrier with the feedstock was carried out directly into the supersaturated solution. Supersaturation was maintained by constantly lowering the temperature. What kind of technology for processing crystals, as stated, ensured sufficient juice of the crystal, Which surprised us about the formation of microorganisms and the diversity of the composition and composition of the crystal between its various zones.

A particular danger at such temperatures is the opening of the crystals during manipulations with the fillers, in addition, with an increase in temperature the width of the metastable zone of the solution decreases. According to well-known technologies, as stated, the metal carrier is placed in a saturated paste and temperature 55-56°. Due to the temperature and undersaturated pasta, the plant in it quickly dissolves. Poet>. To obtain satisfactory crystals, a supercooling of tenths of a degree is required. An increase in the degree of supersaturation of the solution leads to crystal loss and crystallization. All this does not allow us to reliably produce high-quality crystals using known technologies.

In this case, if the insert crystal is selected from the crystals formed at the bottom of the crystallizer, then a loop is pulled into the selected insert crystal, having first secured it to the insert crystal using plasticine, and to create a stand from the composite crystals from a vetically-containing mono-distal, the mono-distal are deposited in crystallization in suspension condition until it reaches the bottom of the crystallization, after which a plastic plate with using plasticine and crystallization cycles continue until crystals of the specified size are obtained.

THE BEST OBJECTIVE FOR EXISTENT IZOBY The proposed method of growing plants at home χ We use the method of extracting copper-slice crystals Сιιδ0 *5Η 2 0 with a purity of 98.5%. Using a reagent of lower purity leads to the formation of flakes in the solution. First, the starter is grown. The starter is grown in a saturated solution. To obtain such a solution, 200 g of the reagent solution is diluted in 800 ml of warm boiled water. If complete quenching is not achieved, it is necessary to heat the solute in a water bath to 50 and it will evaporate Effective without remainder. Extruding the seedling on a bead, using a glass bead or quartz bead. To do this, a fishing line is lowered into the resulting warm solution, acting as a crystal-bearer, a loop is made at one end of the line and a weight is attached. First, the weight is lowered into the solution for 1-12 seconds, after which the weight is taken out and dried. The solution, captured by the truck, when the water evaporates, crystallizes with the formation of many small crystals on the truck. After a few days, when the pasta has cooled down, we again tighten the fishing line with a goose tied to it and keep it safe for two basically at constant room temperature. After the specified time, the solution will pass from the supersaturated to the saturated state, and the excess substance will crystallize on the fishing line with the weight and at the bottom of the crystallizer both in the form of crystal aggregates and in the form of single crystals. Further growth can proceed in two ways: - the disintegration of the crystal deposits formed on the fishing line with the load

For further disintegration of the crystal formed at the bottom of the crystallizer, it is necessary to first insert a fishing line loop into it.

"grows into" the crystal selected for further growing. At this point the process of growing the filler is completed, it is removed from the solution and transferred directly to the process of growing large crystals.

The process is cyclical in nature and the most characteristic points of the cycle are designated in Fig. 1 by the letters A, B, C, O, E. We use the saturated pasta in the room temperature (in Fig. ! - Τ> = Τ κκοмн ), which remained after growing the seedling ( point A in Fig.1). We cook the pasta in a water bath up to 45° (point B, T 3 = 45°). When heated, the solution changes from a saturated to an unsaturated state (АВ). Add 1.5 teaspoons of the reagent, which corresponds to approximately 12 g of copper oxide (ВС). It is necessary to note that the mass must remain unsaturated (point C in Fig. 1). We achieve complete satisfaction

Once you reach a temperature of 8° above room temperature. We introduce into the solution a crystal-bearing substance with a previously grown filler (the process of growing the filler is described above). It should be noted that the solution remains unsaturated until this point. Next, we carry out natural cooling of the unsaturated solution until it is saturated (the point of intersection of the cutoff ϋE with the solution curve), at the same time there is a partial solution of the charge, which contributes to obtaining a higher quality crystal. The cooling duration is several hours.

Along with this, cystalization occurs, the density of which increases and becomes maximum until room temperature is reached (point E). The total duration of the stage of natural cooling of the paste at the moment of entering the all-carrier with the filler (οτροκϋΕ) is about 6 hours. Next, we carry out crystallization in stationary temperature conditions at a constant room temperature. The duration of this stage is three days. In this case, the intensity of the crystallization process constantly decreases as the degree of supersaturation of the solution decreases, and the crystallization process stops at point A, when the solution becomes saturated. After the solution reaches a state of saturation, the crystal carrier with the crystal is removed from the solution and the entire described ASBEA cycle is repeated again. Each cycle can be called a supersaturation technique. To grow a crystal about 10 - 15 cm in size, it is necessary to carry out about 20 supersaturation techniques. To create a stand from a stack of crystals under a vertically standing single crystal, the single crystal is suspended in a crystallizer until it reaches the bottom of the crystallizer. After which a plastic plate is attached to the base of the crystal using plasticine and crystallization cycles continue until crystals of the specified dimensions are obtained. The small crystals formed on the plate cover the plate and form a reliable base for the large crystal.
