Abstract
System and method for producing metal or alloy powder are described comprising an electromagnetic levitating coil having an outlet for supporting a molten source of the metal or alloy and controllably discharging a molten stream thereof, an electromagnetic confining coil disposed at the outlet of the levitating coil and surrounding the molten stream for controlling the diameter of the molten stream, and either an atomization die and associated pressurized fluid source for disintergrating the confined molten stream into molten droplets for subsequent cooling to powder, or a controllable electromagnetic coil surrounding the confined molten stream for generating a downwardly and radially outwardly directed electromagnetic force interacting with the molten stream to form the droplets.
