The excess molar enthalpies HEm of the binary systems MF-NdF3 (M = Li, Na, K) were measured in the present work by high temperature calorimetry on a wide temperature (1220 K < T < 1400 K) and composition range. Some points of the equilibrium phase diagram have been also obtained by differential thermal analysis. Using the Hoch-Arpshofen model we represent the excess quantities of different systems. This will allow us thereafter to calculate the phase diagrams of binary systems NdF3-MF (M = Li, Na).
