Experimental Study on Preparation of Al-Sc Alloy with Sinking Cathode in KF-AlF_3-Sc_2O_3 Molten Salt System AITranslate
Abstract AITranslate
The preparation process of Al-Sc alloy with sinking cathode in KF-AlF3-Sc2O3 molten salt system was studied. The phase composition, microstructure and micro area composition of AI-Sc alloy were analyzed by XRD and SEM. The effects were investigated of electrolysis temperature,cathode current density and molten salt proportion on electrolysis current efficiency. The experimental results show that Al-Sc alloy is composed of Al phase, Sc phase and Al3 Sc phase, and the alloy is mixed with a small amount of mol- ten salt. The distribution and morphology of Al3 Sc phase are irregular in the alloy. The optimal electrolysis process conditions are as follows：in KF-AlF3-Sc2O3 molten salt, liquid aluminum is the sinking cathode, and Sc203 is the electrolyte, with KF/AlF3 molar ratio in the molten salt of 1.3,electrolysis temperature of 800 ℃ ,electrolysis time of 25 min,and current density of 1. 592 A/cm^2. Under the above conditions,Sc content in the Al-Sc alloy is up to 6. 710% and the average current efficiency reaches 57.28%.
