Thermal expansion and specific heat of CaF, which forms the same crystal structure as actinide oxides, were measured by using high-temperature X-ray diffractmeter and differential scanning calorimetry. We confirmed that the specific heat of CaF explicitly shows the effect of excitation on top of the heat capacity at constant volume and dilatational term. The analysis of the specific heat will be discussed together with the measured data.
