Buy now! In differential thermal analysis (DTA), the difference in temperature between the sample and a thermally inert reference material is measured as a function of temperature (usually the sample temperature). Any transition that the sample undergoes results in the liberation or absorption of energy by the sample with a corresponding deviation of .Recently, with the development of the highly-functional polymeric material, these thermal properties analysis needs are increasing dramatically. DTA and DSC detect the temperature differences between the sample and the reference; however, DSC can perform the quantitative measurement of the amount of heat on top.

DTA is a thermal analysis which involves the comparison between the temperatures of sample under investigation and a thermally inert material/reference which may be α-alumina (it is densified alumina in α-phase and occurs in hexagonal structures) and this comparison is then recorded with the furnace temperature as the sample is heated or cooled . What is Differential Thermal Analysis? Differential thermal analysis (DTA) also involves the measurement of both a sample and a reference under a controlled temperature program, but in this case, the temperature .
