Abstract  

The NaPO3−Pr(PO3)3 system was studied by microdifferential thermal analysis (DTA), IR and X-ray diffraction spectroscopies. The only new compound observed in the system is NaPr(PO3)4, which melts incongruently at 1149 K. A eutectic appears at 5% Pr(PO3)3 at 901 K. The new compound NaPr(PO3)4 was characterized by means of powder X-ray diffraction and IR absorption spectroscopy. NaPr(PO3)4 is a NaLa(PO3)4 isotype; it crystallizes in the monoclinic system P21/c witha=12.328(7),b=13.130(5),c=7.231(5) Å, β=126°, 18(5),Z=4,V=945 Ȧ3.
