Abstract

The NaF-LiF-LaF3 system was studied by differential thermal and X-ray powder diffraction analyses. In the system, there are two ternary invariant points, a eutectic (580 ± 2°C, 44.0 mol % NaF, 42.0 mol % LiF, 14.0 mol % LaF3), and a peritectic (595 ± 2°C, 45.0 mol % NaF, 39.0 mol % LiF, 16.0 mol % LaF3). The ternary peritectic point results from the intersection of the crystallization fields of LiF, LaF3, and NaLaF4.
