Combustion of aluminum nanoparticles and exfoliated 2D molybdenum trioxide composites

Al-Based Nano-Sized Composite Energetic Materials (Nano-CEMs): Preparation, Characterization, and Performance

“…A monolayer of two-dimensional (2D) MoO 3 with 3–4 μm thickness was prepared by the ultrasonic dispersion method, and then the nano-sized Al/MoO 3 composite with a high interface contact area by combining Al nanoparticles with 80 nm in diameter was prepared [ 39 ]. The combustion data show that the burning rate reaches (1730 ± 98.1) m·s −1 for their high interface contact area, the increasing rate of pressure is (3.49 ± 0.31) MPa·s −1 , and the temperature in the reacted area is 3253 K [ 40 ].…”

“…The reaction speed of the composition could be slightly improved by introducing gas products through nano-CEMs’ composition design. However, it will bring new problems, such as stability and storage performance [ 1 , 2 , 37 , 38 , 39 ].…”

Multiscale design, interaction mechanism and performance of CL-20/Al energetic composites with embedded structure

“…Compared with the traditional force led, it can describe the potential energy surface more precisely. Herein, the stretching energy is shown in Formula (1): 4 (1)…”

“…Therefore, the preparation of composite energetic materials has become a hot issue in recent years. [3][4][5][6][7] Among composite energetic materials, Al-based composite energetic materials are composed of Al particles and metal, non-metal oxides, organic compounds, etc. The contact between reactant particles in Al-based composite energetic materials is kept closer, which reduces the distance of mass and heat transfer in the reaction process.…”

Dissociative adsorption modes of TATB on the Al (111) surface: a DFT investigation

“…18 To improve the performance of high energetic materials, aluminum (Al) powder is widely used as a metallic additive to explosives, propellants, and pyrotechnic compositions. 19,20 As is known, Al can improve the energy toward the burning reaction in propellants and strengthen the blast effect of explosives. 21,22 The size of Al particles plays a dominant role in the efficiency of these processes.…”
