Title

Evaluation of the Accuracy and Reproducibility of a High-temperature Differential Scanning Calorimeter by Heat Capacity Measurements

Abstract

Differential scanning calorimetry (DSC) is used to determine thermodynamic properties including specific heat, glass transition, and melting points of a variety of materials. The need for accurate determination of thermal properties at high temperatures (>700 °C) has spurred the development of high-temperature differential scanning calorimetry (HTDSC). The introduction of HTDSC increased the upper temperature limit of DSC's capability to 1400 °C, allowing thermal analysis of high-temperature materials such as ceramics and silicates.1 However, the accuracy and reproducibility of HTDSC measurements has not been rigorously studied, especially at high temperatures. In particular, there is a need to determine the impact of experimental variables on the quality of results of HTDSC measurements. Studying the effects of these variables will help generate recommendations for the experimental parameters needed to produce the most reliable results.
