It is a colorless or white solid that is soluble in water. Energetic additives can effectively increase the heat release of ammonium perchlorate (AP) decomposition to prevent nonenergetic additives from decreasing the energy density of composite solid propellants. The effect of atmosphere composition on the rate of decomposition was studied. In this study, copper stearate (CS) was investigated as a potential catalyst for the thermal decomposition of ammonium perchlorate (AP). The most striking of these is that at low temperatures it decomposes only to the extent of about 20 to 30 %, leaving a residue which is chemically identical with the original salt. Thermal analysis demonstrated that the thermostability of 1 was up to 325 °C. The thermal decomposition of ammonium perchlorate has been studied by measuring either the loss in weight, or the pressure increase in a closed system, as functions of time. However, the catalytic mechanism is still controversial and the role of surface lattice oxygen is always ignored. By continuing you agree to the use of cookies. The effect of atmosphere composition on the rate of decomposition was studied. The effects of fullerenes, including fellerene soot (FS), extracted fullerene soot (EFS) and pure C60 on the thermal decomposition of ammonium perchlorate (AP) compared with traditional carbon black (CB) catalyst has been studied by employing thermogravimetry (TG), differential thermal analysis (DTA), infrared spectroscopy (IR) and ignition temperature experiments.

As an energetic accelerator for thermal decomposition of ammonium perchlorate (AP) and ammonium nitrate (AN), 10% nano TAGN blended with AP and AN, and samples “[90% AP + 10% (nano TAGN)]” and “[90% AN + 10% (nano TAGN)]” were obtained, respectively. Adding 10% of NGO to AP decreases the decomposition temperature by 106 °C and increases the … Copyright © 2021 Elsevier B.V. or its licensors or contributors. Herein, a classical catalytic mechanism based on the surface lattice oxygen was proposed to reveal AP decomposition promoted by ZnO nanosheets. This review represents an attempt to summarize literature data on thermal decomposition of ammonium perchlorate. • … Furthermore, the catalytic effect of the obtained samples on the thermal decomposition of ammonium perchlorate (AP) was examined by thermal gravimetric analysis (TGA). The reaction mechanism … The decomposition of ammonium perchlorate and ammonium perchlorate-copper chromite mixtures has been studied in the temperature range from 250°C to 325°C. Field emission scanning electron microscopy, differential scanning calorimetry and thermogravimetry analysis techniques were used to evaluate the coating quality and thermal … ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. The breakdown of … Furthermore, CuO NPs were found to reduce the activation energy of AP decomposition. 31, No. Good recovery of N and Cl was achieved. Because of its use as a solid propellent and more generally in pyrotechnic systems, the thermal decomposition of ammonium perchlorate (AP) has been extensively studied. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Catalytic Activity of Ferrates (NiFe 2 O 4, ZnFe 2 O 4 and CoFe 2 O 4) on the Thermal Decomposition of Ammonium Perchlorate Ming Zhang. Analysis of the former measurements is complicated by concurrent sublimation of the salt. The products of decomposition were identified and the yield of each was established. Copper stearate/ammonium perchlorate (CS/AP) shell–core composite was prepared by in situ synthesis and characterized to sample by SEM and EDS, it shows that CS is evenly dispersed on the surface of AP and forms a shell–core structure. Fengqi Zhao. One of these is the formation of a porous product upon low-temperature thermal decom-position of the orthorhombic phase. Present address: Avco-Everett Research Laboratory, Everett, Mass. The thermal decomposition properties and the heat of combustion (ΔH) of samples with different ammonium perchlorate (AP)/double base propellant (DB) mass ratios under argon atmosphere were studied by the thermogravimetry–differential scanning calorimetry–mass spectrometry–Fourier transform infrared spectroscopy (TG–DSC–MS–FTIR) and automatic calorimeter method. However, the roles of energetic additives are unclear due to their complex changes in the decomposition process. Measurements of the sublimation rate have therefore been made over a wide temperature range and kinetic parameters both for … • Thermal decomposition temperature decreases by more than 100 °C. We use cookies to help provide and enhance our service and tailor content and ads. As a result, on the condition of 5 wt% TCN/CuO, the high decomposition temperature of AP was decreased by 120.6 °C, which is much lower than that of UCN, TCN, CuO and UCN/CuO. g –1 for AP‐CuO‐S, AP‐CuO‐N, and AP‐CuO‐Cl, respectively. Comparison of combustion behaviors of ammonium chlorate and perchlorate. Two simultaneous routes are suggested for the decomposition. Combined with a fuel, it can be used as a rocket propellant. Cr(OH)(3) nanoparticle preparation procedure and its catalytic effect and mechanism on thermal decomposition of ammonium perchlorate (AP) were investigated using transmission electron microscopy (TEM), X-ray diffraction (XRD), thermogravimetric analysis and differential scanning calorimetry (TG-DSC), X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis and … 3, pp. The inclusion of reactive species in AP directly affect the viscoelastic and ballistic properties of the propellant.
