【Abstract】 The current efficiency and DC power consumption in the electrolysis processes to preparation Al-Li master alloy using molten KCl-LiF-LiCl bath was studied. Effects on the current efficiency and DC power consumption of the bath composition, the amount of LiF in the bath, the current density of the cathode, the controlled temperature and the distance of the electrode were investigated in details. The reasonable conditions of the electrolysis were given as: the composition of molten salt WKCl: W (LiCl+LiF) =30: 70, WLiF=2.0%-3.0%, current density on the cathode 1.0-1.4A/cm-2, temperature 993-1073K, and the distance of the electrode should be bigger than 3cm.更多还原
