“…The one endothermic peak detected at 243.12 °C that recognized as the crystal structural transition from orthorhombic to cubic [49].The one exothermic peak for the cubic form arrive at 310.30 °C denotes the partial extinction of AP at lower temperature decomposition and another exothermic decomposition peak noticed at 395.12 °C denotes the complete AP decomposition at high-temperature decomposition. In DSC curves, the necessary increment in the endothermic heat obligation among the two exothermic peaks which fascinated the occurrence of endothermic incident instantly prior to second exothermic decomposition peak of AP [48]. Inclusively, two steps of post transition decomposition comportment observed for AP and it is good agreement with TG and DSC data of AP reported previously [25,[50][51][52][53] to decompose rapidly at lower temperature.…”

In these studies we report the catalytic proficiency of two Eu and Pr doped CeO 2 nanoparticles on the thermal behaviour of powder AP and CSPs samples. A co-precipitation method was used for synthesizing Eu and Pr doped CeO 2 nanoparticles and they were characterized by XRD, FTIR, and SEM with EDX. The catalytic proficiency of both Eu and Pr doped CeO 2 nanoparticles were investigated by utilizing TG-DSC technique. The FWO, KAS, and Starink methods were used to determine activation energies of all catalyzed AP and CSPs samples. The catalytic proficiency increased by addition of Eu and Pr doped CeO 2 nanoparticles and decomposition temperature decreased in the presence of catalyst. The activation energy decreased by the addition of Eu and Pr doped CeO 2 nanoparticles in AP and CSPs, the burning rate of CSPs found to increase by the addition of Eu and Pr doped CeO 2 nanoparticles. The Pr doped CeO 2 nanoparticles showed good catalytic efficiency on AP and CSPs that reduced the decomposition temperature around 70 °C for AP and 20 °C for CSPs. The activation energy of CSPs catalyzed by Pr doped CeO 2 nanoparticles reported 150.12, 147.60, and 146.83 kJ mol −1 by FWO, KAS, and Starink method respectively which decreases in existence of catalyst in CSPs.

“…4b for pure AP with two endothermic peaks was appeared around 307.02 and 390.11 °C. Increased endothermic heat requirement in between the two exothermic peaks appears as a shoulder in the TG graph [48]. While considering TG thermogram of 1 wt% Eu doped CeO 2 nanoparticles added with AP in the Fig.…”

“…The combustion catalyst is another essential component of solid propellant, which has a significant effect for thermal decomposition and combustion performance regulation although its tiny addition amount . Metal oxide, especially nano‐sized metal oxide can effectively promote the thermal decomposition of oxidants, thereby increase the combustion rate and reduce the pressure exponent of solid propellant .…”

Three kinds of ferrates (NiFe2O4, ZnFe2O4 and CoFe2O4) were prepared via the facile solvothermal method and characterized using SEM, TEM, XRD, XPS, FT‐IR and BET instruments. The NiFe2O4, CoFe2O4 and ZnFe2O4 particles possess hollow structure with average particle size of 70, 220 and 360 nm, respectively. The catalytic performance of the ferrates for AP thermal decomposition were studied using DSC and TG‐DTG methods, and the decomposition mechanism of AP were suggested. The catalytic effects of different ferrates for AP thermal decomposition were significantly different. The CoFe2O4 has the best catalytic activity, and the high thermal decomposition peak temperature (THDP) and apparent activation energy (Ea) of AP were decreased by 108.99 °C and 37.38 kJ mol−1 in the presence of CoFe2O4 sample. Adding ferrates has no obvious influence on the gas‐phase decomposition products of AP, but has a great influence on the energy barrier of high temperature decomposition of AP. The excellent catalytic activity of CoFe2O4 is mainly attributed to the synergistic interaction between Fe and Co, which is conducive to the thermal decomposition of AP.

“…The lowest reactivity parameters were obtained for the μ‐Al and n‐B samples (Table ), but high burning enthalpy could compensate this drawback during the combustion process. For comparison, the temperatures of the oxidation peak obtained from DTA‐TG of HMX , CL‐20 and AP decomposition under the same conditions (10 K/min heating rate) are: 285 °C, 270 °C, and 295 °C, correspondingly. The characteristic temperatures of the beginning of decomposition reactions of oxidizers and explosives lay in a temperature range 240–300 °C.…”

But such experimental works focused only on a very limited number of substances like Al , Cu , Ni , Al 2 O 3 , TiO 2 , Fe 2 O 3 (more detailed review of such studies is provided in Table ).…”

Aluminum powders were comprehensively described as the prospective ingredients of the modern propellants. The paper also studied the influence of micro-and nanopowders of metals (μ-Me and n-Me) and metal oxides (μ-MeO and n-MeO) on the burning process of modern aluminized propellant with HMX, CL-20, AP, and active binder. The following metal additives were used: Al, B, Zn, Ni, Co, and Mo. The effect of the following oxides CoO, V 2 O 5 , MnO 2, and Fe 2 O 3 was studied together with LiF. The combustion tests of modified propellant compositions were carried out in the Vielle bomb in a pressure range 2-10 MPa. n-Me addition resulted in an increase in the burning rate by 10 % for n-B, by 30-40 % for n-Ni and n-Mo in the studied pressure range. The introduction of n-Cu caused a burning rate to increase fivefold. n-Zn additive resulted in increasing of the propellant burning rate by 130 % and 260 % at 4 and 10 MPa, respectively. It was probably caused by the catalytic activity of those metals in the gaseous phase. The effect of complex additive was observed to be insignificant for additives with μ-Co 3 O 4 , μ-V 2 O 5 , μ-Fe 2 O 3 and n-Fe 2 O 3 . The burning rate of propellant with n-CuO additive value was higher by a factor of 4 in comparison with the basic formulation in the studied pressure range.
