Kristallographische Daten,IR-Spektrum und thermisches Verhalten von Cer(IV)-Diphosphat

Crystallographic Data, IR Spectrum, and Thermal Behaviour of Cerium(IV) Diphosphate The powder diagramm of CeP₂O₇ has been reinvestigated and the presence of a superlattice was definitively proved. Also the infrared spectrum of the compound has been recorded and interpreted. The investigation of the thermal behaviour of the substance shows that at temperatures higher than 700°C a slow decomposition begins which, under evolution of O₂ and P₄O₁₀ and the intermediate formation of CeP₃O₉, finally gives pure CePO₄.
