نبذة مختصرة : The distillation behaviors of some fission product fluorides in LiCl–KCl system were investigated. For rare earth element, the corresponding decontamination factors (DFs) of Ce in 5 wt% CeF3–LiCl–KCl salts were over 100 at 1040 K and 13 Pa. For SrF2, the very poor DFs was deduced for the presence of more volatile SrClF, while Zr4+ was observed to complex easily with F− and Cl−, which affected its evaporation rate and the separation efficiency. F ion concentration in condensate salt was 1–2 level higher than the metal ion due to the stronger covalent band.
