Study on Solubility of Rare-earth Oxides in LiF-BaF_2-REF_3 System

Solubility of Rare earth mixture oxides in LiF BaF 2 REF 3 system was studied. The effects of composition of molten salt, and its temperature on solubility of Rare earth oxider were investigated.The experiment results prove that solubility of Rear earth is 2% wt～4% wt at 900～1 040℃ range in this system.
