Abstract: On the base of a discussion in all kinds of production methods of Al-Sc alloy, the molten salt electrolysis method was used to produce Al-Sc alloy directively. It is found that as the current density increasing, the concentration of Sc in alloy increases gradually. The maximal concentration of Sc can be 1.5%. But as the MR is increased, the concentration of Sc decreases significantly. When the transited current arrives at a certain extent, cell voltage and back EMF will be increased gradually with increasing eletrolysis process time.
