Aluminum powder had a significant effect on the detonation performance

The size of the aluminum powder significantly affected the detonation performance of explosives. Small-sized aluminum powder is more likely to react with explosive detonation products with an advanced reaction time, large reaction volume, and fast energy release, which enhances the work capacity of explosives. Especially the addition of nano-sized aluminum powder can effectively improve the work capacity of explosives. Leonid Kaled et al. studied Alex nano-aluminum particles and their applications in liquid and solid rocket propellants. It is found that the most effective way to achieve complete combustion is the application of aluminum powder with a particle size of at least 1 to 2 orders of magnitude smaller than the one used in conventional solid propellants. Therefore, research on applying nano-aluminum powder in explosives has attracted more and more attention in recent years. Some researchers have systematically studied the characteristics of RDX-based explosives, such as detonation heat, detonation velocity, metal acceleration ability, underwater explosion energy, front curvature effect, etc. Some papers also reported the influence of nano-Al on the sensitivities of cyclo-trimethylene trinitramine (RDX)-based explosives, which clearly showed that adding nano-Al increased the explosive's mechanical sensitivity and flame sensitivity. However, the research in this field is not deep enough. The results just reflected the macroscopic performance of explosives and some basic theories. The role of microstructure on the materials' performance and relevant scientific theory is yet to be clarified. Until now, the mechanism of NAP inducing the increase in the explosives' mechanical sensitivity and flame sensitivity has not been understood. Previous results have not given enough illustration of the improvement and design of nano-Al-containing explosive formulations.
