Progress on Preparing Al-Sc Master Alloy by Molten Salt Electrolysis

The advantages and disadvantages of direct mixing,thermic reduction and molten salt electrolytic methods,which were used to prepare Al-Sc master alloy,were compared. The progress of preparing Al-Sc master alloy by molten salt electrolysis was discussed. To realize its application,the development effort should concentrate on the fundamental research and the engineering-oriented technique based on the Hall-Heroult molten electrolysis.
