| Abstract Scope |
The three-layer electrorefining of liquid metals utilizing porous holding materials was investigated, which enables to establish a three-layer configuration of metal(l)/electrolyte(l)/metal(l) by holding metals above the electrolyte regardless of their densities. Two-types of electrodes were prepared as upper electrodes. In one approach, porous carbon or silica sheets were used. It has low wettability with liquid Zn and allows molten salt electrolyte to penetrate into its interior. The other method utilized porous Ni. It exhibits excellent wettability with liquid Pb, allowing the liquid Pb to penetrate into its interior. The holding experiments and electrorefining of liquid Zn and Pb were carried out in molten LiCl–KCl–ZnCl2 at 723 K and in molten PbCl2–KCl–NaCl at 773 K, respectively. |
