System and method for manufacture of undercooled metallic core-shell particles

A system for producing metallic core-shell particles, comprising:

• a housing;
• the housing having a hollow interior;
• wherein the hollow interior is configured to receive a molten metal input, a carrier fluid, and one or more reagents;
• a shearing assembly positioned within the hollow interior of the housing;
• wherein the shearing assembly is configured to, when the molten metal input, the carrier fluid, and the one or more reagents are held within the hollow interior and sealed within the 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;
• wherein the shearing assembly includes:
• a shaft positioned within the hollow interior of the housing;
• one or more impellers connected to the shaft;
• and
• a stator positioned within the hollow interior of the housing;
• wherein, when the shaft and the one or more impellers are rotated, the molten metal input is sheared by the one or more impellers.
