Abstract

PURPOSE: To accurately measure heat capacity by surrounding a sample by plural heat insulating shields consisting of the same material as the sample and supplying heating power proportional to the volume of the sample and the shields.
CONSTITUTION: The cylindrical sample 1 is surrounded by the double cylindrical heat insulating shields 7a, 7b consisting of the same material as the sample and heated by supplying current from a DC power supply 8 through a variable resistor 8 and the shields 7a, 7b are directly heated by supplying current from a DC power supply 11. Power proportional to respective volume of the sample 1 and the shields 7a, 7b is supplied so that electric energy per unit volume of the sample 1 coincides with that of the shields 7a, 7b and the internal temperatures of the sample 1 and the inner shield 7b are measured through measuring holes 6, 15, 16 at the same period. consequently, the temperature difference between the sample 1 and the external can be reached to zero as close as possible and the heat capacity of the sample 1 can be accurately measured.
