Webderivative weight curve and can represent the thermal stability of the material. For the materials here, the oxidation temperatures are 411.4±2.7 °C for Material A, 479.0±1.3 °C for Material B, and 492.4±0.7 °C for Material C. Material A exhibited the lowest oxidation temperature and has two peaks in the derivative curve (one WebTGA derivative curve, as well as lower intensity derivative peaks. Both of these subtle differences in the derivative curve are related to the lower surface area exposed to …

A thermogravimetric analyzer continuously measures mass while the temperature of a sample is changed over time. Mass, temperature, and time are considered base measurements in thermogravimetric analysis while many additional measures may be derived from these three base measurements.
