A DTA curve can be used only as a finger print for identification purposes but usually the applications of this method are the determination of phase diagrams, heat change measurements and decomposition in various atmospheres.
DTA is widely used in the pharmaceutical and food industries.
DTA may be used in cement chemistry, mineralogical research and in environmental studies.
DTA curves may also be used to date bone remains or to study archaeological materials.
Using DTA one can obtain liquidus & solidus lines of phase diagrams.
