Abstract : The thermodynamic properties of ternary zirconium-uranium carbide, Zr(x)U(1-x)Cy, having the sodium-chloride type structure were studied using the time-of-flight mass spectrometer. The ratio of the activities of the components was measured as a function of composition at 2440K. From the variation of the ratio of activities with composition, the pairwise interaction energies were obtained. The metal-metal interaction energy = 6.7 plus or minus 0.6 kcal/mole is similar to that in the body-centered cubic zirconium-uranium metallic system. The difference between the zirconium-carbon and uranium-carbon interaction energy is a function of composition. (Author)
