Phase equilibria in the NdBr3-MBr binary systems (M = Na, K) were established by differential scanning calorimetry. The system with NaBr is a simple eutectic system with two compounds that decompose in the solid state (NaNdBr4 at 603 K and Na3NdBr6 at 580 K). In the system with KBr, three stoichiometric compounds exist. First (K3NdBr6) is formed from KBr and K2NdBr5 at 680 K and melts congruently at 918 K. Second (KNd2Br7) melts congruently at 814 K. Third compound (K2NdBr5) melts incongruently at 822 K.
