Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): MOLTEN SALT ELECTROLYTES -- RARE-EARTH METALS -- CHLORIDES Аннотация: Solutions of rare-earth metals (REM, Ln) in molten chlorides, including mixtures MCl + LnCl 3 where M stands for an alkali metal, are studied by methods of potentiometry, voltammetry, and conductimetryin broad intervals of concentration and temperature. The results that had been obtained give sufficiently com-prehensive??and reliable enough information concerning the valence state of rare-earth metals, as well as the struc-tureand composition of complex ions that make a substantial impact on the properties of electrolytes. It is dem-onstrated??that the co-existence of ions of rare-earth metals in different oxidation states, which form as a result ofpossible redox reactions 2 Ln 3+ +Ln 3 Ln 2+ ,Ln 2+ +Ln 2 Ln + ,and nM + +Ln nM +Ln n ,??clearly manifests itself in the thermodynamic and transport properties of molten systems Ln- LnCl 3 –MCl. \\\\Cserver\\dist\\НБО\\Cтатьи БД ИВТЭ\\Russian Journal of Electrochemistry\\2007, V. 43, № 8,С. 961-967.pdf |
