An Investigation Of The Thermal Conductivity, Electrical Resistivity, And Thermoelectric Power Of Thorium Nitride-Uranium Nitride Alloys, Samuel Cavin Weaver

Doctoral Dissertations

Thermal conductivity, electrical resistivity, and thermoelectric. power measurements were made on thorium nitride (ThN), (Th-2% U)N, and (Th-5% U)N; electrical resistivity and thermoelectric power measurements were made on uranium nitride (UN). Results from the experiments indicated that ThN behaves very nearly as a pure metal in its transport properties. Thermal conductivities, λ, were high, electrical resistivities, ρ, were low, and thermoelectric power, S, measurements were nearly zero. Uranium nitride, which antiferromagnetic below 50°K and has a lower thermal conductivity, had a much higher electrical resistivity and a large positive thermoelectric power.

The thermal conductivity of ThN is much higher than …
