ABSTRACT:
An apparatus and method for forming metal powders in which a stream of atomized molten metal is expelled substantially horizontally within a sealed chamber containing a non-reactive gas under pressure, and permitted to free-fall in an arcuate path through the chamber. Atomization is accomplished by use of a nozzle device in which a forced stream of molten metal is cut into droplets by a spiraling jet of the non-reactive gas.
