WebDifferential Scanning Calorimetry (DSC) is used to measure heat flow into or out of a sample as it is exposed to a controlled thermal profile. DSC provides both qualitative and quantitative information about material transitions such as the glass transition, crystallization, curing, melting, and decomposition. For some of these transitions, DSC can WebWhat is the meaning of crystallization peak in DSC?

Webin the DSC. • There is no rigorous way to determine the peak baseline, and the heat of melting is known to be temperature dependent • Simply subtracting the area of the cold crystallization peak (obtained during heating by DSC) from the area of the melting peak would not give an accurate determination [4]. Shown in Figure 2 are the results
WebDSC analysis indicates that two components are needed to accurately fit the crystallization exotherms in the high-temperature range, from 114 to 124 °C. That is congruent with the fact that two crystal structures, α and α′, are formed in that range of temperatures, as reported in a number of works [ 3 , 12 , 14 , 19 , 26 , 27 ].
