Number of the staff: 15 (including 5 research associates, 2 doctors and 3 candidate of sciences).
Directions of research:
development of scientific basis for technologies of highly pure tantalum- and niobium-based materials for electronic engineering;
manufacturing methods for the production of fine-grained tantalum and niobium powders and compounds by metallothermic reduction from their compounds;
production of high-purity tantalum, niobium and other refractory metals by vacuum metallurgy;
studying of the regularities of fine-grained tantalum and niobium powder sintering;
technological patterns designing for the production of advanced tantalum- and niobium-based materials for electrolyticcapacitor anodes.
New technologies and materials:
a technology of tantalum and niobium production by electrolysis of oxofluoride melts;
a technology and a model shop for production of tantalum capacitor sodium-thermal powders with a specific charge of up to 70000 mFV/g (a pilot plant has been built);
a technology and a model shop for production of agglomerated capacitor tantalum powders with a specific charge of up to 8000 mFV/g;
an efficient process of tantalum, niobium, and vanadium powder production from compact metal involving hydration-dehydration with hydrogen in a closed cycle (indus- trially adopted for niobium powder production);
a technology of electrolytic superconducting Nb3Sn coatings;
a method of high-frequency sintering of voluminous-porous capacitor anodes enhancing both their specific charge and quality is commercially adopted for capacitor production;
a commercialized technology of pyrophoric sodium-thermic zirconium powder.
Unique equipment and plants. The vacuum-thermal equipment available in the laboratory includes:
