|Abstract:||The U¿O system has been investigated for almost fifty years, and, in particular, the UO2±x solid-solution phase boundary was considered as established since the beginning of the 1980s. Nevertheless, the results of thermodynamic measurements at temperatures above 2500 K performed with traditional techniques are probably affected by large errors. These are mostly due to reactions of the sample with the containment and to poor control of the equilibrium vapour pressure, with consequent composition instabilities.|
