- new methods for synthesis of rare-element compounds of desired composition, including nano-size powders of ferroelectric materials;
- methods for purification of rare-metal products from radioactive contaminants;
- methods for liquid waste purification;
- electromembrane technologies.
Methods developed
- technologies for lanthanide extraction and separation in the course of a comprehensive processing of locally-available rare-earth minerals (loparite, apatite concentrate and others);
- technology of baddeleyite concentrate purification from radioactive and other impurities, developed in cooperation with JSC "Kovdorsky GOK" mining company;
- solvent-extraction technology for the production of high-purity zirconium compounds from minerals and technogenic wastes;
- methods for synthesizing ferroelectric alkaline element niobates and tantalates, alkali-earth element titanates and zirconates, stoichiometric compounds of the potassium titanyl phosphate subgroup in the form of nano-size powders of narrow grain-size classes;
- deactivation technology for liquid radioactive wastes with increased mineral salt-, suspension- and oil contents;
- n-depth purification of effluents from fluorine ions;
- technologies for rubidium and cesium metals production and deep purification of alkaline metals;
- electromembrane technologies of acid recovery, including hydrofluoric acid, from solutions; production of alkali element hydroxides from respective salts, and utilization of ammoniate-containing solutions.
