Thermal conductivity ( k ), electrical resistivity ( p ), total hemispherical emittance (ε t ), and normal spectral emittance (ε 0.65μ ) of dense, arc‐cast uranium monocarbide (5.3 wt % total carbon) were measured in the temperature range 1150° to 2050°K. The results were as follows: k , 0.057 cal/sec‐cm‐deg, 1200° < T < 2050°K, probable error ± 0.002; p, 20.4 × 10 −6 + 114.8 T × 10 −9 ohm‐cm, 1175° < T < 2050°K, probable error ± 1.7 × 10 −6 ; ε t 0.42, 1250° < T < 1980°K, probable error ± 0.02; ε 0.65 0.539 – 0.02 T × 10 −3 1150° < T < 1890°K, probable error ± 0.02. Experimental methods are discussed and error sources are analyzed. Uranium monocarbide exhibited typical metallic behavior in its thermophysical properties.
