History of the laboratory

The Laboratory of Electrochemical Production Technologies of the Center for Physical and Chemical Methods of Research and Analysis has formally existed since 1996, but many of its scientific developments were developed at the departments of physical and analytical chemistry of the Kazakh State University. Its permanent head and scientific supervisor of all ongoing research is Doctor of Chemical Sciences, Professor A.P. Kurbatov.
Traditionally, the laboratory of electrochemical production technologies carried out work in the field of electroplating aimed at improving technologies for producing coatings for the jewelry industry: nickel plating, copper plating, chrome plating, gold plating and silver plating. Interesting developments have been made in the field of obtaining electroplated copies when forming primary coatings on non-metallic products from which the copy is made, and new electrolytes have also been developed to increase the rate of coating growth. New versions of technologies for metallization of plastics, oxidation of copper, aluminum, nickel and brass products for decorative purposes were also developed here (Moiseevich O.Yu., Galeeva A.K., Sholakova A.N.). All these works, as a rule, were carried out under appropriate contracts with interested enterprises involved in the production of jewelry.
A significant period of scientific activity of the laboratory was devoted to the issues of metallization of polyimide films for printed circuit boards, space mirrors and antennas, technologies for producing metallized microcapsules and self-healing coatings were also developed (Moiseevich O.Yu., Galeeva A.K., Melsitova I.B., Nikolaeva E. .WITH.). This work was carried out under an ISTC grant and two NATO grants in collaboration with scientists from the University of Marseille, the University of Texas, the Moscow Pedagogical University and the Technical University of Montpellier. Work on obtaining self-healing coatings continues to this day within the framework of a grant under the project of the Ministry of Education and Science of the Republic of Kazakhstan “Commercialization of Technologies” with the support of the World Bank.
Interesting both in practical and fundamental aspects are the works on the formation of nanostructures and fractal structures using electrochemical methods of metal deposition (target grants from the Ministry of Education and Science of the Republic of Kazakhstan). Thus, using the example of nickel and copper, the possibility of forming multi-level fractal structures for using them as a matrix of various kinds of electrodes, in particular, for electrodes of electrochemical energy converters (Kamysbaev D.Kh., Melsitova I.B.) was shown.
In matters of hydroelectrometallurgy, the laboratory was mainly engaged in the development of methods for producing metal powders of nickel, copper and zinc. The compositions of electrolytes were improved using additives of surfactants and electrolysis modes were developed to obtain highly dispersed powders (Kobzhanov A.S., Kushnarev M.S.). As an achievement, it is necessary to note not only the technology for producing copper and nickel powders several microns in size, but also the development of a model for the formation of sediment.
Significant work in the field of electrohydrometallurgy is also work devoted to the electrochemical generation of oxidizing agents in sulfuric acid solutions used for the process of underground leaching of uranium. This problem was posed by NAC KazAtomProm JSC. The modes for producing persulfuric acid solutions in a flow electrolyzer were developed, the concentration and electrochemical parameters of the process were optimized (Malchik F., Kalugina S.M.).
