The low-temperature heat capacity of UN was determined by adiabatic calorimetry and found to have a normal sigmate temperature dependence, except for the presence of an anomaly near 52 oK associated with antiferromagnetic ordering of the electron spins. At 298.15°K the heat capacity (Cp), entropy (SO), enthalpy function [(HO-HOo)/T], and Gibbs energy function [-(Go-HOo)/T] are, respectively, 11.43, 14.97, 7.309, and 7.664 calj(gfm.oK).
