thermal analysis

Thermal analysis is a chemistry technique used to study how substances behave when heated. It involves observing the thermal changes, such as heat absorption or emission, that occur as a material undergoes reactions or phase transitions.12

Differential thermal analysis (DTA) is a common method where the temperature of a sample is compared to an inert material as both are heated. Differences in temperature are recorded graphically, creating peaks characteristic of the substance's composition. The size of these peaks can indicate the amount of a substance present, making it useful for identifying minerals and mixtures. Thermal analysis can also be used for qualitative and quantitative analysis by monitoring how a substance's temperature changes during heating, which can reveal decomposition mechanisms.13
