Question

Physical changes are generally indicated by
peak in DTA​

Answer 1

I have done DTA on my powder samples at different heating rates. The curves I got are in microvolts versus time or microvolts versus temperature. I know that the area under a peak indicates the delta-H of the reaction. In fact, in my case with microvolts-temperature, it needs some mathematical calculations according to a reference sample to find delta-H by area of peaks. I do not know about peak height and peak sharpness. Thank you for your help.
