A partial system of NdPO4-NaPO3-Nd(PO3)3 in the ternary system Nd2O3-Na2O-P2O5 was investigated and its phase diagram is proposed. Thermoanalytical methods and X-ray powder diffraction were employed. In the composition range under examination, two ternary compounds occur, which melt incongruently and have the formulae NaNd(PO3)4 (m.p. 866°C) and NaNdP2O7 (m.p. 790°C). Two quasi-binary sections, NdPO4-NaNd(PO3)4 and NaNdP2O7-NaNd(PO3)4 have been identified.
