Electrochemical behaviors of Dy(III) and its co-reduction with Al(III) in molten LiCl-KCl salts

Thermodynamic and electrochemical properties of holmium and HoxAly intermetallic compounds in the LiCl-KCl eutectic

“…Except for the redox couples A/A' and C/C' corresponding to the formation and dissolution of the holmium and aluminum metal, a series of cathodic signals (D, F and G) and their corresponding anodic peaks (D', F', G' and G") can be also observed due to the depolarization of the electrode and deposition of Ho(III) on the previous formed aluminum metal to form Al y Ho x intermetallic compounds and the dissolution of Ho from these Al y Ho x intermetallic compounds, respectively. Similar phenomena were also observed in our previous works about Er [28], Ce [36] and Dy [37] intermetallic compounds.…”

Electrolytic extraction of dysprosium and thermodynamic evaluation of Cu–Dy intermetallic compound in eutectic LiCl–KCl

“…No other peak signal, apart from electrical signals II/II', are found before that of the deposition of metallic lithium, suggesting that the reduction of Dy( iii ) is a one-step process without a co-deposition reaction of Li( i ) and Dy( iii ) ions. The results agree with those reported by Sridharan et al 38 and Shi et al 39 …”

Electrode reaction of Pr on Sn electrode and its electrochemical recovery fromLiCl‐KClmolten salt

“…27,28 Therefore, it is critical to recover and separate lanthanides from molten salt for nuclear fuel cycle and the purification of waste salts. 29 In recent years, the electrorecovery lanthanides from molten salt were explored on various electrodes, for example, Mg, 30 Al, [31][32][33][34] Ni, 35,36 Cu, [37][38][39] Bi, [40][41][42][43] Zn, 38,39,44,45 Cd, 46,47 Sn, 48 Pb, [49][50][51] and Ga. 52 Since there are some advantages to use low melting point metal as a liquid working electrode, many researchers paid more attentions to the electrochemical extraction using a liquid electrode. Our group investigated the electroextraction of Tb and Y from molten chloride using solid Cu and liquid Zn as working electrodes and found that under same conditions, metallic Y and Tb easily deposited on liquid Zn electrode.…”
