    Abstract:

    This paper presents results of investigations of liquidus temperature and solidus temperature of LaF3-LiF molten salts in various compositions which were determined by dynamic thermal analysis. According to the data of liquidus temperature, the structural ions of LaF3-LiF molten salts were studied by the cryoscopic method and the results were compared with previous similar research on the LiF-NdF3 system. The comparisons showed that the phase diagram of LiF-LaF3 (LaF3=0-40% mole) was reliable. LaF4- was identified as the most possible La-F ion in LaF3-LiF molten salts in which LaF3 mole fraction was less than 15%. As mentioned above, in REF3-LiF (RE=La, Nd) molten salts, the anions were F- and REF4-, and Li+ was the only cation.
