The heat capacity of cadmium has been determined by adiabatic calorimetry from 298.15 to 700 K. The heat capacity of solid cadmium at 594 K is approximately 5% higher than recommended in the evaluation by Hultgren-recently accepted without change by Barin and only slightly modified in a CODATA evaluation. For liquid cadmium the presently obtained heat capacity is about 6% higher at 600 K than proposed by the same authors. The enthalpy of fusion derived from two series of experiments is 6166 +/- 18 J mol(-1). The thermodynamic properties of cadmium at selected temperatures are derived.
