Abstract

The thermal diffusivity, thermal conductivity and spectral emissivity at 0.65 μm of uranium carbide have been measured with the aid of a modulated electron-beam apparatus. For hypostoichiometric samples, a reversible, time-dependent oxidation-reduction of the surface interfered with the measurements between 1100 and 1400°C, without affecting the results. Expressions are derived representing the thermal diffusivity, thermal conductivity and spectral emissivity for stoichiometric and for slightly hypo- and hyperstoichiometric uranium carbide.
