Introduction:
DTA:Differential Thermal Analysis is a technique which can measure the temperature difference and temperature relationship between the sample and the reference material in the process control temperature. Differential thermal analysis curves can describe the relationship of the temperature difference △T changes with the temperature or time between the sample and the reference material. During the DTA experiment, the sample temperature changes due to the endothermic or exothermic effect of the phase transition or reaction. Such as, phase transition, melting, crystalline structure transition, boiling, sublimation and evaporation, dehydrogenation, cleavage reaction or position reaction, oxidation or reduction reaction, the destruction of lattice structure and the other chemical reaction.
