ABSTRACT:
Powdered metal of improved cleanliness and uniformity of particle size is produced by directing a stream of the molten metal into a container having peripherial walls formed of a porous material, such as ceramic foam, having a network of fine passageways extending therethrough. The container is rotated to centrifugally force the molten metal through the porous peripherial walls of the container and to eject the molten metal from the container in the form of fine droplets while inclusions present in the molten metal are filtered and retained in the porous ceramic material, and whereby a metal powder is formed upon cooling and solidifying of the droplets.
