that the behavior of the rare-earth fluorides, YF,, and BaFz in both LiF and the LiF-BeF2 mixture studied can be approximated by assuming Raoult's law. The deviation of SrF, and, in the binary sys- tern, LaF3 from this pattern is unexplained. 241 The relative volatilities of the fluorides of the rare earths, yttrium, barium, and sf rontium ace low enough to allow adequate removal in a still of simple design. Zirconium removal, however, will be iris ignifican t. Table 20.2.
