Electrochemistry of Zn and co-reduction of Zn and Sm from LiCl–KCl melt

Abstract

SEM image and element mapping analysis of Zn–Sm alloy obtained by galvanostatic electrolysis.

Electrochemical properties of yttrium on W and Pb electrodes in LiCl–KCl eutectic melts

“…For example, the electrode area is changeless, and the diffusion of deposited metal into the liquid metal is easier. 6,7 Thus, liquid Ga, [7][8][9][10][11] Bi, [12][13][14][15] Cd, 13,16 Zn, [17][18][19][20][21][22][23][24] Sn 25 were selected as cathode to separate REs from molten salts. The melting point of Pb metal is 600 K and boiling point is 1798 K, it is easy to melt but doesn't evaporate at 723-823 K. Thus, Pb metal seems to be a good candidate as the cathode material in separation and extraction of REs by molten salt electrolysis.…”

Facile Electrochemical Preparation of Al-Sm Alloys in Molten Calcium Chloride

“…6 Sm-Zn alloys can be obtained directly by the co-electroreduction of Sm(III) and Zn(II). 7 Al 3 Sm intermetallic compound was produced through the co-deposition of Sm(III) and Al(III). 5 Whatever, there has barely reported about a more reasonable electrochemical preparation process of Sm metal or alloys from solid oxides.…”

Electrochemical Extraction of Praseodymium by Formation of Zn-Pr Alloy in LiCl-KCl Melts with the Assistance of ZnCl2and Liquid Zn

“…The thermodynamic dates such as activity coefficient and formal standard potential were obtained. Yan et al [18][19][20][21][22] investigated the electrochemical properties of rare earth elements of thulium, lanthanum, ytterbium and samarium in chloride molten salts, and successfully prepared M-RE (M = Mg, Zn) alloys with the assistance of MgCl 2 and ZnCl 2 .…”
