Abstract

High-temperature differential scanning calorimetry was used to investigate the thermodynamic parameters of the γ–β and β–α transitions in calcium pyrophosphate (Ca2P2O7). The measured enthalpy of transition compared well with previous results when higher heating rates (≥20 K min−1) were used. Recommendations for optimal use of HTDSC in high-temperature phase transition measurements are presented.
