摘要
The enthalpy increments of PuPO4 have been measured using drop calorimetry in the temperature range from 530 K to 1386 K. The heat capacity was derived from the obtained data and compared with heat capacity data obtained directly from differential scanning calorimeter measured in this study from 400 K to 1400 K. The recommended heat capacity of PuPO4 was determined based on both techniques as: C-p(0) (J K-1 mol(-1)) = 126.600 + 32.999 x 10(-3) (T/K) - 1.9503 x 10(6) (T/K)(-2). (C) 2011 Elsevier B.V.
