Abstract

The electrochemical behavior of Gd3+ in LiCl-KCl eutectic system on a tungsten electrode was studied, relevant thermodynamic and kinetic properties of the Gd3+/Gd redox reaction were investigated by chronopotentiometry and improved open-circuit chronopotentiometry techniques. The results showed that the Gd3+ reduction on a tungsten cathode occurred in a single step pattern. The apparent standard enthalpy and entropy for the GdCl3 formation were calculated to be -1030.475 kJ/mol and -198.2 J/K, and the diffusion coefficient was 0.62×10-5 cm2/s at 691 K.

Key words： electrochemistry; LiCl-KCl molten salt; gadolinium trichloride; tungsten electrode
