Abstract

Rare earth (REM, Ln) solutions in chloride melts including MCI+LnCl{sub 3} mixtures, where M - alkali metals, were investigated by potentiometry, voltammetry, conductometry in wide concentration and temperature intervals. Findings present complete and trusty information on the valent state of rare earths, structure and composition of complex ions affecting essentially on properties of electrolytes. It is demonstrated that the coexistence of rare earth ions with different oxidation level formed as a result of possible redox reactions: 2Ln{sup 3+} + Ln {r_reversible}3Ln{sup 2+}, Ln{sup 2+} + Ln{r_reversible}2Ln{sup +} and nM{sup +} + Ln{r_reversible}nM + Ln{sup n+} appears sharply in thermodynamic and transport properties of molten Ln-LnCl{sub 3} and Ln-LnCl{sub 3}-MCl systems.
