| Abstract: | 5-Amino-1H-tetrazole (5-AT), as a new type of green energetic material, has a wide range of applications in firefighting and gunpowder. Pyrolysis serves as a critical prerequisite for the combustion process. Understanding the pyrolysis mechanisms of 5AT-based solid propellants is essential for further elucidating their combustion characteristics. In this paper, 3, 5, and 10% of boron–magnesium alloys were mixed with 5-AT/Sr (NO3)2 to investigate the effect of boron–magnesium alloys on the pyrolysis behavior of 5-AT. Thermogravimetric differential scanning calorimetry and Fourier transform infrared spectroscopy experiments were performed on the samples to investigate their thermal behavior. The kinetic parameters of the samples were determined using the Kissinger–Akahira–Sunose and Starink methods. Additionally, the pyrolysis mechanism model was predicted using the Coats–Redfern method. Furthermore, the thermal safety of the samples was evaluated based on the DSC curves. The results demonstrate that the addition of boron–magnesium alloys significantly impacts all three stages of 5-AT pyrolysis, altering the pyrolysis model in each stage. Specifically, the addition was found to promote the pyrolysis decomposition in the first stage while suppressing it in the third stages. Moreover, the pyrolysis mechanisms for each stage were also modified. Besides, the addition of boron and magnesium alloys enhanced the thermal safety of the samples. Finally, a comparative analysis of the three catalysts with varying concentrations revealed that the addition of 5% boron–magnesium alloy provided the best catalytic performance and the most stable thermal safety. These findings offer a theoretical foundation for the modification and pyrolysis pathway analysis of 5AT-based solid propellants. [ABSTRACT FROM AUTHOR] |
