Abstract
Gd2Cl3 is electrocrystallized from molten GdCl3 at 900 K with a current efficiency of 70% referring to the reaction 2GdCl3+3e⁻=Gd2Cl3+3Cl-. The reaction is used to determine cocrystallization coefficients for trivalent rare earths and actinoids (Y, Nd, Cm, Pu), divalent lanthanoids (Eu, Yb), and Sr. The oxidation potential for the above reaction is determined as 2.65 ≤ E° ≤ 2.68 V.Keywords
