Abstract (en)
A process for producing finely divided spherical metal alloy powders comprises forming an aqueous mineral acid solution containing at least one metal, forming a metallic material from the solution, reducing the metallic material to metal powder particles, subjecting the metal powder particles to a high temperature zone to melt a portion of the particles to form droplets and cooling the droplets to form essentially spherical metal particles.
