Study of the thermal properties of different phases of zirconia has been reported. Tojo et al experimentally
measured the specific heat capacity at constant volume [9]. They investigated the thermal properties of pure
zirconia and YSZ by adiabatic calorimetry measurement at a temperature range between 13 K and 300 K. Several
attempts were made to investigate the properties and the phase transition nature of zirconia [10, 11] using density
functional theory (DFT). Lou et al [12] investigated the thermodynamic properties and temperature based
monoclinic to tetragonal phase transition for both ZrO2 and HfO2 using ab initio method. The temperature
dependency of heat capacity of two materials was validated.
