The heat capacity of vacuum greases has been measured by laser-flash calorimetry at a temperature region from 80 to 400K. Both Apiezon-N and -T showed an anomaly in heat capacity from 220 to 320K, while silicone grease showed a sharp anomaly around 230K. The best choice of a vacuum grease is discussed for the use in maintaining thermal contact between sample and light-absorbing disk in laser-flash calorimetry.
