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.

摘要: A continuous method of manufacturing a liquid dispersion containing submicron metal or metal compound particles inside a liquid bath. A metal-containing fluid with carrier gas mixture is bubbled through the liquid bath and predetermined conditions in the bath cause the fluid to decompose to form the submicron sized metal or metal compound particles in the liquid.
