Abstract
A system and method are presented for producing metallic core-shell particles. The system includes the housing having a hollow interior configured to receive and hold a molten metal input, a carrier fluid, and one or more reagents. The system also includes a shearing assembly positioned within the hollow interior of the housing. The shearing assembly is configured to, when the molten metal input, carrier fluid, and one or more reagents are held withing hollow interior and sealed within housing, shear the molten metal input into particles of an effective size so that a shell created on a surface of the particles via reaction with the one or more reagents prevents a core of the particles from solidifying when the particles are cooled to a temperature below a freezing temperature of the molten metal input.
