On the existence of a two-phase field in the uranium oxygen system. within the composition range 2.65 O/U < 2.67 below 1273 K.

Abstract

The purpose of this work was to further investigate the existence, or not, of a two-phase field between UO 2.65 and UO 2.67 below 1273 K. It was carried out making use of equipment recently developed in our laboratory useful for equilibrium thermogravimetric measurements of PO2, as a function of composition and temperature. A convenient fixed temperature was chosen for our measurements, namely 998 K.
