Molar heat capacity and thermodynamic functions of zirconolite CaZrTi2O7
BF Woodfield, J Boerio-Goates, JL Shapiro… - The Journal of Chemical …, 1999 - Elsevier
Zirconolite (CaZrTi2O7) has been proposed as a host phase for excess weapons plutonium,
and the standard molar entropy Δ0298. 15 KSmoand other derived thermodynamic functions
are needed to describe it completely. The heat capacity of CaZrTi2O7has been measured
fromT≈ 20 K toT≈ 400 K with an adiabatic calorimeter. A six-term fitting equation based on
Debye and Einstein functions has been shown to represent the heat capacity over the entire
range of temperature to within the experimental uncertainty. This equation has been used to …
