This study investigates the feasibility of using an Al-Si eutectic alloy as a reactive fuel in energetic mixtures. Al-Si eutectic alloy powders were obtained from secondary resources and ground to a particle size of less than 100 μm. We examined these powders' burning characteristics and thermal properties compared to pure Al powder. Results showed that the burning rate of energetic mixtures containing Al-Si eutectic alloys was 1.5 to 2.0 mm/s higher than those with pure Al. Additionally, the activation energy of pure PTFE was reduced from 81.29 kJ/mol to 61.75 kJ/mol when the Al-Si alloy was added. The formation of oxides, carbides, and fluorides in the combustion products of Al-Si-based mixtures significantly influenced their thermodynamics.
本研究探讨了使用铝硅共晶合金作为含能混合物中的反应性燃料的可行性。铝硅共晶合金粉末取自二次资源，并研磨至粒径小于100μm。我们将这些粉末的燃烧特性和热性能与纯铝粉进行了比较。结果表明，含铝硅共晶合金的含能混合物的燃烧速率比含纯铝的混合物高1.5至2.0mm/s。此外，添加铝硅合金后，纯聚四氟乙烯的活化能从81.29kJ/mol降至61.75kJ/mol。铝硅基混合物燃烧产物中氧化物、碳化物和氟化物的形成显著影响了它们的热力学。
