Abstract

 In this study, the thermal decomposition of ammonium perchlorate (AP) with the coating of nano-manganese oxalate (MnC2O4•2H2O) gel has been investigated. The Coating of nano-manganese oxalate has characterized by X-ray diffraction (XRD). The image of the sample obtained by scanning electron microscope (SEM) has indicated a uniform coating of MnC2O4•2H2O on the ammonium perchlorate particles. At the beginning, non-agglomerated nano-manganese oxide has been prepared from nano-manganese oxalate during the thermal decomposition of ammonium perchlorate (AP) and then has been considered as a nano-metal oxide catalyst on the thermal decomposition of ammonium perchlorate using differential scanning calorimetry (DSG) and thermal gravimetric analysis (TG). The results have shown that the decomposition temperature of ammonium perchlorate in the presence of nano-manganese oxide has reduced from 417 to 311oC through the mechanism of electron transfer. In addition, the result of TG analysis is used to evaluate the theoretical kinetic parameters (Eaa and logAa) by Flynn–Wall–O method.
