    摘要: A process for the production of extra fine spherical metal powders by chemical vapor deposition and dissolution techniques, including metal carbonyls, wherein the metal containing process gas is propelled upwardly through a heated reactor. By employing an upward gas flow as opposed to the conventional downward gas flow, a closer approximation of theoretical plug-flow velocity profiles are achieved thusly resulting in a desirably narrower size particle distribution obviating or reducing the need for subsequent classification techniques.
