“…Due to delayed ignition, such agglomerates cannot often burn during the limited time. 13 Thus, a large portion of the particles remains unburned, dramatically reducing the efficiency of the system. 33 Besides, agglomeration can increase the diffusion distance between fuel and oxide.…”

“…The effects of particle size and agglomeration of CuO on the thermal behavior and ignition kinetics of Mg-CuO thermite systems are investigated. 13 The activation energies for the Mg-CuO thermite systems are estimated by applying isoconversional method. Besides, CuO nanowires, with diameter about 30-100 nm and length about 15 μm, are synthesized with the application of a vapor-phase approach.…”

In this work, thermal properties and kinetics of Al-nanoparticles/α-MnO 2 nanorods thermite were reported. The α-MnO 2 nanorods were synthesized using a hydrothermal method and were characterized by X-ray powder diffraction (XRD) and X-ray photoelectron spectra (XPS), then combined with Al nanoparticles based on the ultrasonic mixing method to prepare the nanostructure thermite. Besides, both pure components and mixture were characterized by field emission scanning electron microscopy (FE-SEM) to observe their morphologies and structures. Subsequently, the thermal properties of Al/α-MnO 2 nanostructure thermite were studied on the basis of thermogravimetric-differential scanning calorimetry (TG-DSC). According to the TG-DSC tests, the calculation results of activation energy for kinetics of Al/α-MnO 2 thermite were obtained using different isoconversional methods. It was found that Al/α-MnO 2 nanostructure thermite has high heat release and low onset temperature, and the heat release of the nanostructure thermite was approximately 1146.6 J g -1 .

“…The analysis of articles dealing with nanothermites shows that many researchers dry the nanothermite suspensions by natural evaporation of the liquid in air [66][67][68][69][70]. This method is not recommended, as in these conditions, the nanoparticles have time to organize in a non-random, albeit uncontrolled manner.…”

Nanothermites are the most important family of energetic materials in contemporary pyrotechnics. This article traces the main research which was carried out in this still recent domain and the challenges that remain to be overcome. The academic effort of past two decades has brought nanothermites from the status of laboratory curiosities to the one of pre‐industrial materials. Different aspects of nanothermites are discussed in order to provide valuable information to scientists experimenting in this domain. Experimental details on the preparation and the disposal of nanothermites are reported. The current research on nanothermites deals with: (i) the development of new aluminothermic mixtures; (ii) the preparation of hybrid compositions by combining nanothermites with explosive nanopowders and (iii) the study of reactive properties. From an academic standpoint, the future challenges are to find new compositions and effects. From a practical standpoint, the effort must focus on the integration of nanothermites and their derivatives in pyrotechnic systems. Toxicological concerns are expected to become increasingly important over the next decade.

“…1 As for fuel selection, although powdered magnesium is easy to ignite with bright ame, it is dangerous to use nano-scale powdered magnesium in practice due to its spontaneous combustion in the sunshine, even without any open re. 2,3 On the other hand, the volumetric heat of combustion of aluminum powder is much higher than that of magnesium powder. 4 Therefore, nano-Al is more widely used in energetic nanocomposites than nano-Mg.…”
