Sample Type on Decomposition of Ammonium Perchlorate

摘要

Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) have been used to study the thermal decomposition of ammonium perchlorate samples in the form of 2mm monocrystals, 265μm, and 3μm powders; and pellets pressed to 4 and 7 tons. TGA and DSC techniques have been employed to examine the effect of sample type on the kinetics of the process. The effects have been evaluated as changes in the temperature, reaction heat, and the rate of decomposition. Isoconversional kinetic analysis has been carried out to detect changes in the effective activation energy of the process.
