“…Although the exact mechanism of AP's decomposition is not yet known, it is proposed that AP decompose as follows: (i) At LTD, NH 4 ClO 4 is dissociated to NH 4 + and ClO 4 − , which then by proton transfer forms NH 3 and HClO 4 . The decomposition of HClO 4 and NH 3 to various gaseous oxides leads to a major exothermic event responsible for HTD of AP 3,6,8 …”

“…Usually, additives that decrease the decomposition peak temperature of high energetic materials lead to lower activation energy; however, it is not true in all cases. Hence, three heating rates should be used to get accurate values 4–8 . Kinetic parameters were calculated using thermal data at three heating rates using the isoconversion method (Kissinger–Akahira–Sunose [KAS] method), details of which can be found somewhere else 15 .…”

“…That is, according to Hanafi et al, 5 the production of hydrazine NTO (HNTO) and AN cocrystal can result in cocrystal with improved heat release during decomposition at a lower temperature, which can be further boosted by adding triaminoguanidine‐cobalt containing graphene oxide catalyst. The integration of iron oxide, nano thermites, graphene oxide‐based composites, and other energetic formulations such as cocrystals and energetic composites can improve the thermal breakdown of energetic materials 3–8 . AP is a well‐known high energetic material often used in solid propellants.…”

BaZnCuO3 (BZC) was synthesized using the sol–gel method. The BZC was incorporated in reduced graphene oxide (rGO) to produce BZC/rGO composite. The synthesized catalysts were characterized using Raman, scanning electron microscopy (SEM), powder X‐ray diffraction (XRD), and ultraviolet–visible (UV–Vis) analysis. The comparative effect of BZC and BZC/rGO composite was studied on the thermal decomposition of 3‐nitro‐3H‐1,2,4‐triazol‐5‐one (NTO) and ammonium perchlorate (AP) using the simultaneous thermogravimetric technique (TG‐DTA). Thermal investigations suggest that BZC was a better catalyst for decreasing the thermal decomposition temperature and the thermokinetic parameters of both AP and NTO compared to BZC/rGO composite. BZC can reduce the thermal decomposition temperature of AP and NTO by 121 and 46°C, respectively. The findings support BZC as a possible catalyst in the thermolysis of both NTO and AP.

“…A greater influence of DEGDN can be observed for the TBC modified granules, when the lowest activation energy value of the decomposition process was obtained. The activation energy of NC-DEGDN system was about 135 kJ mol À 1 [54,55]. In contrast granules containing ATEC or TBC and DEGDN were characterized by a higher activation energy than binary system NC-DEGDN.…”

Nitrocellulose granules containing the proposed new eco‐friendly inert plasticizers, substitutes for phthalate derivatives, such as acetyl triethyl nitrate (ATEC) and tributyl citrate (TBC) were obtained. The single‐base propellants were obtained using safe granulation process (water method). Diethylene glycol dinitrate (DEGDN) was used as an energetic modifier in obtained propellants. It was found that the addition of citrate plasticizers reduced the heat of combustion and dynamic vivacity of powders. At the same time DEGDN increased the heat of combustion of tested materials. Citrate derivatives did not affect the density and thermal decomposition of granules. It was concluded based on pyrostatic analysis that the TBC plasticizer influenced the kinetics of nitrocellulose gelatinization by DEGDN. The kinetic model [nth order with autocatalysis (CnB) reaction] was adjusted based on the process of thermal decomposition. The presence of DEGDN in granules reduces the activation energy and increases the constant heat cumulative rate. The prepared propellants are characterized by excellent thermal stability in accordance with the STANAG 4582 standard. The obtained propellants can be potentially used in small calibre ammunition.

This study explored the stability and thermo‐kinetic features of double base nitrocellulose (NC)/diethylene glycol dinitrate (DEGDN) propellant supplemented with Kraft lignin. For this purpose, the impact of 2‐nitrodiphenylamine (2‐NDPA), 1,3‐dimethyl‐1,3‐diphenylurea (C‐II) and lignin stabilizers on the molecular structure, morphology, and thermokinetic behavior of NC/DEGDN composite were thoroughly analyzed. Experimental results showed that lignin exhibits promising stabilizing efficiency comparable to that of the conventional 2‐NDPA and C‐II. In addition, thermal findings highlighted that the incorporation of 2‐NDPA, C‐II, and lignin has improved the thermal decomposition temperature of NC/DEGDN propellant. The investigation of the thermolysis kinetics of stabilized NC/DEGDN composites demonstrated an increase in the Arrhenius parameters with respect to the NC/DEGDN baseline. Above all, this investigation contributes to the ongoing efforts to develop new environmentally friendly stabilizers for nitrate esters‐based composites.
