Collected Applications of Thermal Analysis
DSC Model Free Kinetic Analysis of Decomposition of Ammonium Perchlorate
The kinetics of the thermal decomposition of the cubic ammonium perchlorate (AP) has been extensively studied. The reported effective activation energies vary from about 371 to 2602 kJ mol-1. The mechanistic interpretation of the values is also different. The confusing character of the kinetic information is not surprising for the process that is known3 to be a tangled interplay of various chemical (solid-state decomposition, reaction of gaseous products with the solid, gas-phase reactions) and physical (diffusion, sublimation, adsorption-desorption) processes.
