Differential thermal analysis (DTA) is a technique to measure the temperature difference and temperature relationship between a substance and its reference substance under programmed temperature control.The dTA curve describes the temperature (T) between the sample and the reference as a function of temperature or time.In DTA tests, sample temperature changes are caused by endothermic or exothermic effects of phase transitions or reactions.Such as: phase transformation, melting, crystal structure transformation, boiling, sublimation, evaporation, dehydrogenation, fracture or decomposition reactions, oxidation or reduction reactions, lattice structure destruction and other chemical reactions.
