“…Our finding for the eutectic composition agrees with the literature information quite well (x = of about 0.436, as estimated from the graphic form of the phase diagram), whereas our eutectic temperature is lower by 7 K. The effect in the solid phase was observed by us at temperature 603 K, and it was ascribed to decomposition of NaNdBr 4 compound into NaBr and NdBr 3 in the solid state. This compound has a completely different stoichiometry from that assumed in the literature [41], where it was defined as either Na 3 NdBr 6 or Na 2 NdBr 5 . Additional thermal effect at 580 K, observed for the first time by us, was not reported in the literature.…”

Phase equilibria in the NdBr 3 -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 (NaNdBr 4 at 603 K and Na 3 NdBr 6 at 580 K). In the system with KBr, three stoichiometric compounds exist. First (K 3 NdBr 6 ) is formed from KBr and K 2 NdBr 5 at 680 K and melts congruently at 918 K. Second (KNd 2 Br 7 ) melts congruently at 814 K. Third compound (K 2 NdBr 5 ) melts incongruently at 822 K.
