| Abstract Scope |
Magnesium nanoparticles (NPs) hold strong promise as high-performance reactive materials due to their favorable thermodynamic and kinetic properties. However, their reactivity is hindered by a diffusion-controlled oxidation mechanism, where magnesium must diffuse through a native oxide shell to react with an oxidizer. To overcome this limitation, we modified the Mg surface using two approaches. First, we used nonthermal plasma to hydrogenate Mg NPs synthesized via in-flight condensation. Upon hydrogen release, a fresh metallic Mg surface is exposed, which readily oxidizes to trigger ignition. Second, we functionalized the Mg NP surface with a Ni coating. This Ni layer undergoes an intermetallic reaction with Mg, generating localized heating and significantly lowering the ignition temperature. These surface modifications enable ignition at temperatures as low as ~200 °C, significantly improving reactivity compared to unmodified Mg particles. This work presents a promising strategy to enhance the ignition behavior and tunability of Mg-based energetic materials. |
