“…The present paper reports on the new achievements in the development of the technology for electrochemical production of non-ferrous metals in chloride melts presented in previous papers [ 20 , 21 , 22 ]. The electric conductivity and liquidus temperature of the molten KCl–PbCl 2 [ 20 ] and CsCl–PbCl 2 [ 21 , 22 ] systems containing lead oxide have been measured. Three types of laboratory electrolytic cells for electrorefining of metallic Pb containing Sb and Bi have been developed and tested [ 23 ]: the electrolytic cell with a bipolar metallic electrode, the electrolytic cell with two anodes and one cathode, and that with a porous diaphragm.…”

An anode dissolution of binary metallic lead–bismuth alloys with different concentrations of components has been studied in the KCl–PbCl2 molten eutectic. The dissolution of lead is found to be a basic process for the alloys of Pb–Bi (59.3–40.7), Pb–Bi (32.5–67.5), Pb–Bi (7.0–93.0) compositions in the whole interval of studied anode current densities. A limiting diffusion current of lead dissolution was observed at 2 A/cm2 and 0.1 A/cm2 for the alloys of Pb–Bi (5.0–95.0) and Pb–Bi (3.0–97.0) compositions, respectively. The dissolution of bismuth takes place at the anode current densities exceeding the mentioned values. The number of electrons participating in the electrode reactions is detected for each mechanism. Based on the theoretical analysis, the experimental electrolysis of bismuth was performed in the laboratory-scale electrolytic cell with a porous ceramic diaphragm. The final product contained pure bismuth with a lead concentration of 3.5 wt.%.

“…11 Thermodynamic properties of the dilute solutions of lead (II) oxide in the KCl-PbCl 2 equimolar mixture 12 and phase equilibria in the ternary KCl-PbCl 2 -PbO system elucidate that the temperature of primary crystallization increased from 409 • C in the system without PbO to 533 • C in the melt with 8.0 mol% of PbO. 13 There is a lack of data on the PbO interaction with chloride melts obtained by the in situ methods and the question about the melt structure remains undetermined.…”

Thermal analysis was applied to determine liquidus temperatures in the CsCl–PbCl2 (18.3 –81.7 mol%) eutectic mixture with the PbO concentrations ranging from 0 to 20 mol%. The temperature dependence of the PbO solubility in the CsCl–PbCl2 (18.3–81.7 mol%) eutectic melt was studied, and the thermodynamic parameters of the PbO dissolution were calculated. The type, morphology, and composition of oxychloride ionic groupings in the melt were determined in situ using Raman spectroscopy.
