“…This is similar to the results of Cornet and Kappesser[23], but the transition from constant to increasing Sh occurs at Re = 200 and Sh was equal to 37 in the constant regime. Burgman and Sides[9,10] also experienced increasing Sh at Re values less…”

The application of the rotating cylinder electrode (RCE) to molten LiCl-KCl eutectic mixtures for electroanlytical measurements is presented. This enabled the measurement of the limiting current which was observed to follow a linear trend with the rotational rate raised to 0.64-0.65 power on average, which closely agrees with existing RCE mass-transfer correlations. This is the first publication of electroanalytical RCE measurements in LiCl-KCl eutectic based molten salt mixtures, to our knowledge. These measurements were made in mixtures of molten LiCl-KCl eutectic containing UCl 3 and MgCl 2. Kinetic parameters were calculated for Mg 2+ in LiCl-KCl eutectic. The exchange current density (i o) of Mg 2+ deposition varied with mole fraction (x) according to i o (A cm-2) = 1.64x 0.689. The parameters from RCE measurements were also applied in an electrochemical co-deposition model entitled DREP to detect and predict the deposition rate of U and Mg. DREP succeeded in detecting the co-deposition of U and Mg, even when Mg constituted less than 0.5 wt% of the deposit.

“…1000<Re<100,000), as demonstrated in aqueous solutions [5]. The RCE has been employed extensively in aqueous solutions [6][7][8] and has also been applied in cyrolitebased melts [9,10], but no reported RCE studies could be found on eutectic LiCl-KCl.…”
