Abstract

Abstract

The common problems and causations for errors during high-temperature specific heat capacity tests by the simultaneous thermal analyzer (STA449F3) were analyzed. The specific heat capacity was tested using a three-step method with differential scanning calorimetry. The results showed that the errors between confirmed and tested values can be decreased by improving the instrument stability and heating rate. Furthermore, if the conventional one-stage temperature rising test was divided into several narrow temperature ranges, then the accuracy of high-temperature specific heat capacity tests was improved.
