| Outline of Final Research Achievements |
In the thermic reduction of oxide XOx-1(s)(X = Ti, Zr, or difficult reducibility metals) using electrodeposited liquid metal (Me = Ca, Li, or their alloys), the presence of dissolved Me at the vicinity of the cathode is essential, when the oxide is placed close to the cathode. To understand the transient behavior of Me droplets in the molten salt bath, the interface between the electrodeposited phase and the bath system was observed in-situ using a high-speed digital microscope. Further, the transient behaviors of multi-fluid system were investigated using the SPH model. We found that the droplets on the electrode are slightly flattened, when the colloidal Me content decreases. This mechanism indicates that the heterogeneous distribution of the colloidal Me may be due to the local Me solubility in the electrolyte.
