A process for the uniform evaporation of metals is accomplished by rotating a substantially cylindrical refractory element through a source of molten metal to coat the surface of said element with a thin film of molten metal, heating a portion of the molten metal coated surface of the refractory element to a temperature sufficient to vaporize at least a portion of the metal thereon. Condensing the metal vapors thus produced on a cooler substrate produces a solid metal film thereon. Passing the metal vapors into a cooler space containing an inert gas under low pressure or submicroscopic nucleic particles produces metal powders.
