Abstract

Pyrochlore samarium hafnate was synthesized by reverse precipitation with final annealing at 1823 K, and identified by X-ray powder diffraction (XRD), chemical analysis, and electron microscopy. Relaxation calorimetry and adiabatic calorimetry were used to measure the molar heat capacity in the range 4–347 K. The temperature-dependent entropy, enthalpy increment, and reduced Gibbs energy were calculated. The general form of the Schottky anomaly at low temperatures was determined.
