摘要

摘要: The decomposition kinetic parameters of ammonium perchlorate (AP) having different grain size (10-390μm) were investigated through simultaneous DSC/TGA (differential scanning calorimetry/thermal gravimetric analysis) analyzer in a dynamic nitrogen atmosphere under heating rate of 40K/min.The kinetic parameters such as activation energy and pre-exponential factor were determined by the modified isoconversional method.The Brurzauer-Emmett-Teller (BET)-method was applied to measure AP specific surface areas.The results show that the higher the AP particle size the lower the determined kinetic parameters and are matched with some important literatures.
