Abstract

Quantitative relationships between chemical kinetics and DTA curves are studied for the reactions which follow the general rate expression: r = r₀e^-E/RT(1 - x). Both the frequency factor and the activation energy can be derived from a single DTA curve. From the known kinetic parameters, the DTA curve can also be predicted. The rather simple models developed in this work have been tested by the oxidation reaction of nuclear graphite with CO₂ and by data in the literature on the thermal dehydration of clays. The results are satisfactory considering the complexities involved in DTA.
