Abstract: The phase equilibrium diagram of the system Na₄P₂0₇—Zn₂P₂0₇ was •determined by means of hot-stage microscopy, DTA, and X-ray powder diffraction. The system is of quasi-binary character. There is one intermediate compound in it (Na₂ZnP₂0₇) which melts congruently at 805°C. It crystallizes in the tetragonal system with unit cell parameters о = 7.6919(9) A, с =10.2726(8) A.
