Novel aluminum-based fuel:Facile preparation to improve thermal reactions
文献摘要：
To improve the thermal properties of aluminum(Al)in the energetic system,a coated structure with ammonium perchlorate(AP)was prepared by a facile approach.And N,N-Dimethylformamide(DMF)was chosen as an ideal solvent based on heterogeneous nucleation theory and molecular dynamics simulation.This coated structure could enlarge the contact area and improve the reaction environment to enhance the thermal properties.The addition of AP could accelerate oxidation temperature of Al with around 17.5℃.And the heat release of 85@15 composition rises to 26.13 kJ/g and the reaction degree is 97.6％with higher peak pressure(254.6 kPa)and rise rate(1.397 MPa/s).An ideal ratio with 15 wt％AP was probed primarily.The high energy laser-induced shockwave experiment was utilized to simulate the reaction behavior in hot field.And the larger activated mixture of coated powder could release more energy to promote the growth of shockwave with higher speed up to 518.7±55.9 m/s.In conclusion,85@15 composition is expected to be applied in energetic system as a novel metal fuel.
