Phase equilibria in the partial system CePO4K4P2O7KPO3

The CePO4K4P2O7KPO3 portion of the oxide Ce2O3K2OP2O5 system has been investigated using thermoanalytical methods, powder X-ray diffraction, XPS and IR spectroscopy. The phase diagram with liquidus isotherms and isothermal section at room temperature of the system CePO4K4P2O7KPO3 has been determined. One section, CePO4K5P3O10, which is quasi–binary only in the subsolidus region (below 560 °C), have been found. The system contains one double phosphate K4Ce2P4O15, which exists only in solid state, below 880 °C.
