An improved apparatus for the production of particulate metal is disclosed. The apparatus includes a containment vessel having a sidewall and a bottom plate, a source of metal external to the vessel, nozzle means carried by the bottom plate and providing communication between the vessel and the external source of metal, and release means associated with the sidewall to inhibit deposition of the particulate metal on the sidewall.

Apparatus is provided for the production of atomized metal comprising a containment vessel having a sidewall terminating in a bottom plate through which atomizing gas and molten metal from a molten metal source external to said vessel enter said vessel through nozzle means sealed thereto. An air ingress port is provided in the vessel spaced from said bottom plate; the sidewall and bottom plate cooperating with said nozzle means to seal off the interior of the vessel and the metal particles therein from the area adjacent the source of molten metal; thereby providing an essentially closed vessel, particularly with respect to the area in which the nozzle means are mounted.
