چکیده

In this work, we report the thermal kinetics, thermodynamics, and decomposition mechanism of AP-based molecular perovskite energetic materials estimate their safety performance. Typical materials, (H 2 dabco)[NH 4 (ClO ) 3 ] (DAP-4), pz)[NH ](PAP-4), mpz)[NH ](PAP-M4), hpz)[NH (PAP-H4), were synthesized characterized. These studied using differential scanning calorimetry (DSC). The results show that all obtained have higher temperatures, peak temperatures are more than 360 °C. All follow random nucleation growth models. Other thermodynamic parameters, such as reaction enthalpy (?H), entropy change (?S), Gibbs free energy (?G), they generally thermodynamically stable. Moreover, adiabatic induced obtained; T D 24 DAP-4, PAP-4, PAP-M4, PAP-H4 246.6, 201.2, 194.5, 217.5 °C, respectively. This study offers an important in-depth understanding characteristics potential applications.

Kinetics of Thermal Decomposition of Cubic Ammonium Perchlorate

The methods of thermogravimetric analysis (TGA) and differential scanning calorimettry (DSC) have been used to study the thermal decomposition of ammonium perchlorate (AP). TGA curves obtained under both isothermal and nonisothermal conditions show a characteristic slowdown at the extents of conversion, R ) 0.30-0.35. DSC demonstrates that in this region the process changes from an exothermic t...

The Role of Boron in Thermal Decomposition of Ammonium Perchlorate

Simultaneous thermal analysis (STA) method has been applied to study decomposition reactions of AP under a flowing nitrogen atmosphere and static air. Results obtained indicate that a phase transformation occurs prior to the decomposition reaction. Decomposition takes place exothermally in two stages, first stage of decomposition could be suppressed by the controlled heating programme. Addi...

Combustion Mechanism and Kinetics of Thermal Decomposition of Ammonium Chlorate and Nitrite

Combustion data of ammonium chlorate and nitrite have been analyzed. The leading reactions of combustion of both NH4ClO3 and NH4NO2 at low pressures have been shown to proceed in the condensed phase, with the burning rate defined by the decomposition kinetics at the surface temperature. The kinetics of NH4ClO3 and NH4NO2 decomposition have been calculated by using a condensed-phase combustion m...
