THERMODYNAMICS FOR COMPATIBILITY STUDIES OF METAL-CLAD URANIUM CARBIDE
Thermochemical data for the carbides of molybdenum, niobium, tantalum, titanium, tungsten, uranium, and zirconium were critically reviewed, and the free energy of formation as a function of temperature was calculated for these carbides. On the basis of these data, metal claddings of niobium, tantalum, titanium, and zirconium would be expected to react with uranium carbides in the temperature range of 1000 to 2000 deg C. Data are insufficient to predict the behavior of molybdenum, but tungsten should not react extensively with stoichiometric UC below 1800 deg C. The monocarbide (UC) is the most stable of the uranium carbides in contact with the metals listed, and U/sub 2/C/sub 3/ and UC/sub 2/ would be expected to react with all the metals over the entire temperature range of 1000 to 2000 deg C.
