Abstract
A mixture of anhydrous sodium sulfate, hydrated nickel phosphate, and sodium phosphate has been synthesized and various techniques used to characterize it. Differential scanning calorimetry was used to investigate the thermal properties in both O2 and N2 atmosphere at rate of 10 K min−1. The specific heat capacity was calculated from 298 K to 573 K and vice versa in two thermal cycles in both atmospheres, revealing values of 18,931.64 J kg−1 K−1 in O2 atmosphere and 15,568.39 J kg−1 K−1 in N2 atmosphere in the second thermal cycle, being exothermic in nature in both cases. This exothermic behavior of the mixture indicates its potential use as a heat-dissipating material. The crystallite size of this inorganic heat-dissipating mixture was found to be ~ 22.9 nm.
