The Self-cooling Effect

Part of the Hot Topics in Thermal Analysis and Calorimetry book series (HTTC, volume 7)

The role of self-cooling in endothermic decompositions has been discussed in many works. However, only in a few studies [1–3] performed during the period 1930–1950 has this effect been taken into account in measurements of dehydration rates and of the corresponding Arrhenius parameters (E and A). Most of the other researchers assume (often implicitly) that the magnitude of self-cooling is insignificant and may be neglected. Much greater attention has been given to the problem of self-heating during the processes of pyrolysis, carbon gasification, and decomposition of high-energy materials.
