Reactive & Energetic Metal Powders
We design and synthesize ultrasonically atomized Al-based alloy powders with tunable reactivity. By controlling alloy composition and post-processing, we engineer powder microstructures — core–shell architectures, precipitate distributions, surface oxides — to prescribe ignition and combustion behavior. A growing focus is sustainable green hydrogen production: tailoring recycled aluminum-alloy powders to split water and release hydrogen on demand, so that energy can be stored and transported as a stable metal powder instead of as compressed or liquefied hydrogen. In-operando high-speed holography and pyrometry link microstructure to combustion response, and correlative characterization via SEM/EBSD, TEM, and FIB underpins all stages of this program.
