Из результатов вольтамперных измерений следует, что потенциалы выделения La и Co на вольфрамовом электроде, покрытом предварительно выделившимся кобальтом, различаются более чем на 1,0 В. Поэтому электрохимический синтез интерметаллидов La и Co возможен только в кинетическом режиме. Разработан способ высокотемпературного электрохимического синтеза порошков интерметаллидов лантана и кобальта в галогенидных расплавах. Выявлены условия реализации совместного электровосстановления ионов La3+ и Co2+, на основе которых показана принципиальная возможность прямого электрохимического синтеза интерметаллидов лантана. Установлено, что механизм электросинтеза определяется условиями проведения электролиза. В потенциостатических условиях (при потенциалах отрицательнее потенциалов выделения более электроотрицательного элемента – лантана) имеет место совместное выделение La и Co, и процесс синтеза определяется энергией активации реакции взаимодействия лантана с кобальтом на катоде. В целом процесс электросинтеза интерметаллидов на основе La и Co определяется взаимосвязанными параметрами – составом электролитической ванны и напряжением на ней. Проведен высокотемпературный электрохимический синтез ультрадисперсных порошков интерметаллидов на основе лантана и кобальта (Сo3La2, Сo7La2, Co13La) из хлоридных расплавов.</p></abstract><trans-abstract xml:lang="en"><p>The paper studies the combined electroreduction of lanthanum LaCl63–and cobalt CoCl42– chloride complexes in an equimolar KCl–NaCl melt at a tungsten electrode. As it follows from the results of voltampere measurements, potentials of La and Co reduction at a tungsten electrode coated with preliminary reduced cobalt differ by more than 1,0 V. Therefore, the electrochemical synthesis of La and Co intermetallics is possible only in the kinetic regime. The paper develops the method for the high-temperature electrochemical synthesis of lanthanum and cobalt intermetallic powders in halide melts. The paper determines conditions for realization of the combined electroreduction of La3+ and Co2+ ions, on the basis of which the paper demonstrates the principal possibility of the direct electrochemical synthesis of lanthanum intermetallics. The paper establishes that the electrosynthesis mechanism is determined by electrolysis conditions. Under potentiostatic conditions (when potentials are more negative than potentials for reduction of the more electronegative element – lanthanum) the combined reduction of La and Co takes place, and the synthesis process is determined by the activation energy of the interaction reaction between lanthanum and cobalt at the cathode. In general, the electrosynthesis of La- and Co-based intermetallics is determined by the following interrelating parameters – the composition of the electrolytic bath and the voltage across it. The paper describes the high-temperature electrochemical synthesis of lanthanum- and cobalt-based ultrafine powders of intermetallics кобальта (Сo3La2, Сo7La2, Co13La) from chloride melts. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрохимический синтез</kwd><kwd>ультрадисперсные порошки</kwd><kwd>интерметаллиды лантана и кобальта</kwd><kwd>хлоридный расплав</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electrochemical synthesis</kwd><kwd>ultra-fine powders</kwd><kwd>lanthanum and cobalt intermetallics</kwd><kwd>chloride melt</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Министерство образования и науки Российской Федерации (гос. задание № 2011/54)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ito T., Ido H.
