AI Technical Summary
The combustion mechanism of thermite mixtures, including nano- and micro-energetic particles, is not well understood, particularly in dispersed phases where oxygen availability is not a limiting factor, and this limits their application in various technologies.
The use of core-shell thermite particles, which contain both fuel and oxidizer within a discrete particle, allowing combustion to occur through solid-state diffusion, independent of gaseous oxygen, and can be combusted in a dispersed group using modes such as incipient, partial, critical, and external particle combustion.
This approach enables efficient heat generation in environments without gaseous oxygen, applicable to additive manufacturing, propulsion systems, power generation, and space technologies, among others, by leveraging the self-sustaining combustion of core-shell nanothermites.
