摘要：

The temperature dependence of the PuF3, AmF3, CeF3, and NdF3 solubility in the eutectic 46.5LiF-11.5NaF-42KF was measured in the interval 550-700A degrees C. Anhydrous plutonium, americium, cerium and neodymium trifluorides were synthesized. The method of isothermal saturation with dissolution of pressed PuF3, AmF3, CeF3, and NdF3 pellets in melt in an inert argon atmosphere was used for the measurements. It was found that the solubility of trifluorides is high and strongly dependent on the melt temperature. The following values of the solubility were found 700A degrees C: PuF3 30, AmF3 43, CeF3 32, and NdF3 37.
