Abstract: The heat capacity from 5 to 350 K of IrO2 has been measured by quasi-adiabatic equilibrium calorimetry. The values for the thermodynamic properties at 298.15 K have been calculated as Cp, m(T)/R = 6.687, [Delta]0TSmo/R = 6.133, [Delta]0THmo/(R [middle dot] K) = 1039.5, and [Phi]mo(T, 0)/R = 2.647. The low-temperature heat capacity shows typical metallic behavior with an electronic coefficient [gamma]/R = 0.00067 K-1. The entropy at 298.15 K is shown to be consistent with the volumetric dependence of this quantity.
