The oxygen electrode in fused lithium chloride-potassium chloride eutectic containing oxide ion

Electrochemical behaviour of neptunium in the molten LiCl–KCl eutectic

“…This indicates that the bath was free of dissolved O 2À (redox potential close to $+0.2 V versus Ag/AgCl at 450°C [24,25]). Cyclic voltammetry and chronopotentiometry experiments were carried out in a solution of NpCl 3 (2.53 · 10 À5 mol cm À3 ) in the molten LiCl-KCl eutectic in the 400-550°C (673-823 K) temperature range.…”

Quantitative analysis of Eu2+ and Eu3+ in LiCl–KCl eutectic melt by spectrophotometry and electrochemistry

“…In the present study, we used an electrochemical method to remove O 2À impurity from the melt based on Eq. (5) [25,26]. Fig.…”

Thermodynamics of the O2/O2− redox couple in molten (LiCl+KCl+Li2O) systems

“…In order to understand chemical and electrochemical behavior of oxide ion, it is indispensible to measure the thermodynamic quantities of oxide ion such as chemical potentials in molten chlorides. Some researchers previously reported on the oxygen electrode reaction in molten chlorides [3][4][5][6][7], however, these results did not coincide with each other, which was attributed to the fact that an oxygen evolution selective electrode on which the oxygen evolution only occurs without side reactions such as dissolutions of the electrode at high temperatures was not available. That is why thermodynamic consideration on the electrochemical processes involving oxide ion such as reduction processes of MOx (M = U, Si, Ti, etc.)…”
