In order to find accurate heat capacities over a wide temperature range using a convenient method, examinations were carried out under various conditions using Heat-Flux DSC. The following results were obtained.
(1) The precision for the measurement depends on following conditions, heating rate, heating interval, sample weight and temperature range.
(2) The heating interval conditions do not influence the precision of the heat capacity measurement from 20°C to 400°C.
(3) The precision for heating measurements was the same as for cooling ones.
(4) Over the temperature range from -20°C to 700°C, the precision of the heat capacity of corundum agreeded with the values given in the literature within 1%RSD.
