Quasibinary section NdPO4–Na3PO4 has been investigated by thermoanalytical methods (DTA, TG, DTG), X-ray powder diffraction and microscopy. Its phase diagram is proposed. It is found, that the parent orthophosphates react in the molar ratio 1:1 yielding an intermediate compound of Na3Nd(PO4)2. This phosphate melts incongruently at 1485C, giving NdPO4 and an Na3PO4-rich liquid. Na3Nd(PO4)2 compound is stable down to room temperature and exhibits a polymorphic transition at about 1040 graduate C.
