In a high-speed fabrication process for producing highly uniform ultra-small metallic micro-spheres, a molten metal (16) is passed through a small orifice (30), producing a stream of molten metal (32) therefrom. A series of molten metal droplets forms from the breakup of this capillary stream. Appli...
