摘要
Electrochemical and thermodynamic properties of Nd, Sm, Eu, Tm, and Yb chlorides in melts of individual LiCl, NaCl, KCl, and CsCl, of 3LiCl-2KCl, LiCl-KCl-CsCl, NaCl-KCl-CsCl, and NaCl-2CsCl eutectics, and of the equimolar NaCl-KCl mixture in the temperature interval 573-1173 K were studied by stationary and nonstationary methods. The mechanism of reduction of lanthanide(III) ions to metal was elucidated, and the main kinetic and thermodynamic characteristics of the process in alkali metal chloride melts were calculated. The influence of the ionic potential and polarizing power on the behavior of lanthanides in molten salts of various cationic compositions was determined. © 2013 Pleiades Publishing, Ltd.
