Abstract
Measurements of CO pressure over the thorium dioxide, thorium dicarbide, carbon phase region were made in the range 1328–1976 K. These values were used with other consistent measurements to derive the 298 K second-law heat of formation and entropy 129±6 kJ/mol and 67.0±3 J·mol−1·K−1, and the third-law heat of formation −122±9 kJ/mol, for thorium dicarbide.
