Phase Equilibria in the Oxide Nd2O3-K2O-P2O5 System. The Quasibinary System NdPO4-K3PO4
Phase diagram of NdPO4-K3PO4 quasibinary system has been elaborated based on investigation by thermoanalytical methods, X-ray powder diffraction, IR spectroscopy and microscopy in reflected light. One binary orthophosphate of the formula K3Nd(PO4)2 occurs in this system, and it melts incongruently at ~1415 graduate C. The compound appears in two polymorphic modifications (transformation alfa/beta-K3Nd(PO4)2 proceeds at 1150–1175 graduate C) and is stable down to room temperature.
