Specific heat capacity measurement at high temperature by thermal radiation calorimetry

Abstract

Specific heat capacity measurement was performed for a disk-shaped specimen by means of a technique of thermal radiation calorimetry. The specimen whose surfaces are blackened is heated by double flat heaters in a vacuum chamber. The heat capacity is derived only by measurement of the specimen temperature and the heater temperature on both heating and cooling modes. The simultaneous measurement of heat capacity and dielectric constant associated with phase transition was performed for advanced ceramics.
