Selective extraction of titanium from Ti-bearing slag via the enhanced depolarization effect of liquid copper cathode

Quantificational 4D Visualization of Industrial Electrodeposition

“…In the parameter setting, the initial diffusion coefficients in the solid Ni and liquid Ga were set on the orders of 1 × 10 −15 m 2 s −1 and 1 × 10 −10 cm 2 s −1 , respectively. [41] The simulation results (Figure 5) well agree with our experimental findings, which verifies the hypothesis that the fast diffusion of Ti atoms into liquid Ga electrode would induce the Ti dendrites. Because of different dendrite size, the larger dendrite (2#) would be largely maintained on the surface of Ga electrode, while the smaller ones (1# and 3#) would be dissolved.…”

“…In the electrometallurgy, it is noticeable that liquid metal electrodes attracted increasing attention because of their outstanding merits, such as selective reduction, [ 40 ] UPD, and dendrite inhibition, etc., compared with solid electrodes. Subsequently, we employed liquid Ga as electrode for studying the kinetic process of Ti electrodeposition.…”

“…The profile decreased immediately at the initial stage, and then remained stable, demonstrating a good stability of the interface between the liquid Ga and electrolyte. [ 15 , 30 , 41 ] 3D reconstructed images of the Ga working electrode at different electrolysis time are given in Figure 4a , where three distinct mesoscale Ti dendrites (circled by green dotted line and numbered a, b, and c) were tracked by X‐ray tomography, which is different from the mesoscale smooth surface of the Ni. Obviously, such unusual phenomenon is rarely found in the conventional results, specifically in the case that the mass of the deposited Ti is far less than that of the liquid Ga electrode.…”

Electrochemically Converting Liquid Cu2S‐Sb2S3 to Liquid Cu2Sb and Sulfur in Molten Salt at 730 °C

“…The rapid formation of liquid Cu−Sb alloy benefits from the preformed liquid Sb (Step 2, Figure 7). The dual impacts between the alloying effect and Ostwald ripening are regarded as crucial factors in forming the homogeneous alloy [24] . When the desulfurization of molten sulfide was completed, the final liquid alloy (Cu 2 Sb) formed (Step 3, Figure 7, and Figure 5 g and h).…”

“…The dual impacts between the alloying effect and Ostwald ripening are regarded as crucial factors in forming the homogeneous alloy. [24] When the desulfurization of molten sulfide was completed, the final liquid alloy (Cu 2 Sb) formed ( Step Significantly, choosing propitiate cell voltage and electrolysis duration can avoid the co-deposition of Na or K and thereby obtain the target liquid alloy. On the other hand, the selectively alloying can be used to selectively remove a specific impurity metal from alloys (Figure S10).…”
