Measurement of the heat capacity of ZnSb by DSC between 300 and 673 K. (December 2016) - Benigni, P.
Abstract: The heat capacity of the thermoelectric ZnSb compound is measured by DSC (Differential Scanning Calorimetry) using the small temperature steps method in the [300–673 K] range. The sample is prepared by direct melting and compacted by Spark Plasma Sintering. The results match with previous data relative to similar polycrystalline samples. The Neumann-Kopp rule is obeyed considering the experimental margin of error. As for pure Zn and Sb, a significant departure from the Dulong-Petit limit is observed. Highlights: New measurements of the heat capacity of the thermoelectric ZnSb compound on a polycrystalline sample by DSC. Use of the accurate small temperature steps method, validation of the experimental protocol on pure silver. The Neumann-Kopp rule is obeyed.
