ABSTRACT:
A method and apparatus for producing metal powder in which a reducing liquid is introduced into the bottom of a substantially closed granulation chamber, and a reducing gaseous atmosphere is produced above the reducing liquid. A stream of molten metal is introduced into the top of the granulation chamber and is acted upon by one or more jets of a pressurized atomizing agent which atomizes the molten metal stream. Metal particles are cooled at least partly in the reducing gaseous atmosphere and are collected in the reducing liquid in the bottom of the chamber, from which they can be withdrawn.
