Useful method to analyze data on overall transformation kinetics
Source abstract
Abstract
Abstract We propose an easy and reliable method for analyzing data from DTA and DSC studies of crystallization at constant heating rate, q. It is demonstrated that important information can be obtained in log-log coordinates of plot of heating rate, logq, against peak temperature, logTp. The slope of the corresponding straight line is proportional to the dimensionless activation energy ℰ. It is demonstrated that there is a simple relation between the characteristic crystallization time τ, the heating rate q and the peak temperature Tp.
