Description

The thermochemical properties of Cs2U4O12 have been evaluated using new experimental data, including the low-temperature heat capacities, the enthalpy of formation at room temperature, and the high-temperature enthaply increments by drop calorimetry. From the results a section of the Cs-U-O phase diagram at 1000 K has been constructed showing the stability of the compound as a function of cesium and oxygen pressure. (orig.)

Abstract (German)

Unter Verwendung neuer experimenteller Daten, einschliesslich der Waermekapazitaeten bei niedriger Temperatur, der Bildungsenthalpie bei Raumtemperatur und der Enthalpieinkremente bei hohen Temperaturen durch Fallkalorimetrie, wurden die thermochemischen Eigenschaften von Cs2U4O12 bestimmt. Aus dem Ergebnis wurde ein Ausschnitt des Phasendiagramms fuer Cs-U-O bei 1000 K aufgestellt, der die Stabilitaet der Verbindung als Funktion des Caesium- und Sauerstoffdruckes zeigt. (orig.)
