Electrochemistry and Thermodynamics of EuCl3 and EuCl2in Alkali Chloride Melts

Abstract

The electrochemical redox process Eu(III) + e Eu(II) in NaCl-KCl, KCl and CsCl melts in the temperature range 973-1123 K on glassy carbon electrodes was studied by linear sweep voltammetry and cyclic voltammetry. It was determined that in alkali chloride melts at a polarization rate of v?0.1 V s-1, the electroreduction of Eu(III) to Eu(II) is reversible, but at 0.1
