High-temperature heat capacity measurements can be a very powerful means to investigate and understand the properties of materials, high-temperature heat capacity values are also the key thermodynamic data can be used for calculating phase diagram, chemical reaction, and multi-phase equilibrium. As one of the most promising method, drop calorimetry has attached much attention during the past years due to its special 3D thermal sensor, which provides more accurate measurement of high-temperature heat capacity. All the subsequent insightful analyses and further discussion should be based on correct experimental data. A few critical concerns about high-temperature heat capacity measurements by Drop calorimetry were summarized in this study. Various possibilities in the measurements will be given to shown how much the experimental data deviated from their exact values, and those concerns should be taken seriously during actual measurements in order to obtain reliable high-temperature heat capacity values.
