Systems of Ba(PO3)2-Sr(Pu3)2, Cd(PO3)2-Ca(PO3)2

Phase diagrams of the Ba(PO3)2-Sr(PO3)2 and Cd(PO3)2-Ca(PO3)2 systems have been studied and plotted by the methods of differential-thermal analysis (DTA), visual-polythermal, X-ray phase and infrared spectroscopy. The Ba(PO3)2-Sr(PO3)2 system is of the eutectic type. In the binary system Cd(PO3)2-Ca(PO3)2 the existence of a continuous series of solid solutions with a minimum at 858 deg C and 27.5 mol.% Ca(PO3)2 has been established
