Abstract

The process of Al-Ce alloy prepared by electrodeposition was studied in molten LiF-KCl-CeF₃ salt at 820 °C. Several process parameters such as back electromotive force and current efficiency were measured by continuous pulse oscillograph. The results showed that the back electromotive force increased with the increase of the current intensity. With the addition of 2 wt.%Ce₂O₂, the back electromotive force decreased by 0,26 V on average, and increasing temperature could make the back electromotive force decrease as well. The back electromotive force changing period with feeding measured was 50 min. Finally, at 820 °C, the largest current efficiency (68.8 %) was obtained by electrolyzing for 2 h at 4 A.
