Trends of research:
- studying of the mechanisms and kinetics of electrode processes, the nature of chelation in halide and oxohalide melts;
- chemistry and electrochemistry of rare refractory and rare-earth metals in molten salts;
- methods of electrochemical synthesis and analysis of new compounds involving control of the chemical and phase composition of products and the composition of the complex first- and second coordination spheres, as well as creating various-function materials with enhanced physical and chemical properties for specialized branches of engineering;
- methods for determining the quality of epitaxial coatings involving optic microscopy and electronic microscopy on the basis of ‘Metam PB-21 device and Video-Test image analyzer.
New technologies and materials:
- a series of composite materials, obtained by galvano-diffusion, with mechanical and electric characteristics realized through the steel or copper substrate, while a fine surface layer of tantalum, niobium, hafnium and other rare metals functions as a diffusion barrier or protection of the composite in aggressive medium;
- advanced materials with a surface of rare- or rare-earth metal alloys of desired phase composition, obtained by the galvano-diffusion method;
- high-temperature electrochemical synthesis, extremely advantageous for the production of rare-metal compounds (borides, carbides, silicides, nitrides, oxides and oxofluorides) affording to control the valent state of rare metals in compound;
- by using electrorefining, highly pure rare metals (outstandingly pure in terms of some of the impurities) have been obtained;
- a technology of depositing a fine rare-metal film on non-conducting materials – glass and ceramics – has been developed;
Production and introduction.:
- technology of depositing barrier and protective coatings;
- misch metal production;
- electrorefining of chromium and scandium;
