摘要

在1328-1976 K范围内测量了二氧化钍、二碳化钍、碳相区域的CO压力。这些值与其他一致的测量值相结合，得到二碳化钍的第二定律生成热为298 K，熵为129±6 kJ/mol和67.0±3 J·mol−1·K−1，第三定律生成热为- 122±9 kJ/mol。

High-temperature equilibrium between thorium dioxide, thorium dicarbide and carbon

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.
