Solubility of UF4, ThF4, and CeF3 in a LiF-NaF-KF melt

The solubility of UF 4 , ThF 4 , and CeF 3 in fluoride melt of the composition 45 mol % LiF-12 mol % NaF-43 mol % KF in the temperature interval 773–973 K was determined. The solubility of the fluorides increases with an increase in the melt temperature. The CeF 3 solubility in the LiF-NaF-KF system...

Zusammenfassung:	The solubility of UF 4 , ThF 4 , and CeF 3 in fluoride melt of the composition 45 mol % LiF-12 mol % NaF-43 mol % KF in the temperature interval 773–973 K was determined. The solubility of the fluorides increases with an increase in the melt temperature. The CeF 3 solubility in the LiF-NaF-KF system is high: 19.9 mol % at 923 K and 23.3 mol % at 973 K. Experimental data on the solubility of CeF 3 (PuF 3 imitator) were compared to the calculated data on the PuF 3 solubility in the LiF-NaF-KF melt. The results showed that CeF3 can be considered as PuF3 imitator in FLINAK melt.
