Abstract: NaCl-KCl(equimolar)-ScCl3system was chosen as the electrolyte, 3-factor quadratic common rotation combination orthogonal design was employed to investigate the effects of temperature,t, current density,J, and the content of ScCl3in the molten salt,w(ScCl3), on the content of Sc in the Al-Sc alloys, w(Sc), and the current efficiency,ηI, in the preparation of Al-Sc alloy with molten salt electrolysis. The regression functions of the relationships of ω(Sc) and ηI with t,J and ω(ScCl3) were set up. Under the conditions chosen in the experiments,w(Sc) andηIcan reach about 8% and 85% respectively.
