✦ Synopsis

The heat capacity of calcium has been measured at 85 mean temperatures between T 1 8 K and T 1 369 K using an adiabatically-shielded calorimeter in an intermittent heating mode. At T = 298.15 K, the recommended values for the molar heat capacity, molar entropy, and molar enthalpy increment referred to T = 0 are (25.77 2 0.08) J•K -1 •mol -1 , (42.90 2 0.11) J•K -1 •mol -1 , and (5811 2 12) J•mol -1 , respectively. The uncertainties are twice the standard deviation of the mean.

Calcium titanate, CaTiO 3 , has appeared as a significant impurity in the synthesis of several ceramic host materials for the disposal of excess weapons grade plutonium and uranium. Previously reported heat capacities on CaTiO 3 extend only to T = 50 K. Also, the agreement of the low-temperature hea
