Measurements were made of (CO) pressure over (UC/sub 1-x/O/sub x/) at 1823, 1773, 1673, 1573, and 1473 K for various values of x, in the presence of (UC/sub 1/ /sub 86/). The data were used to model (UC/sub 1-x/O/sub x/) as a solid solution of (UC) and (UO), where deltaG/sup xs/ is represented by an expansion in two terms, the first of which is temperature-dependent. The model allows for the accurate prediction of chemical activities and phase equilibria in regions also containing (UC/sub 1/ /sub 86/), (UO/sub 2-y/), (UC/sub 1/ /sub 86/)-(UO/sub 2/), and (UO/sub 2-y/)-(U).
