Abstract:
Atomization processes for manufacturing a metal powder or an alloy powder having a melting point comprising of about 50° Celsius to about 500° Celsius are provided herein. In at least one embodiment, the processes comprise providing a melt of a metal or an alloy having said melting point of about 50° Celsius to about 500° Celsius through a feed tube; diverting the melt at a diverting angle with respect to a central axis of the feed tube to obtain a diverted melt; directing the diverted melt to an atomization area; and providing at least one atomization gas stream to the atomization area. The atomization process can be carried out in the presence of water within an atomization chamber used for the atomization process. In at least one embodiment, the processes provide a distribution of powder with an average particle diameter under 20 microns with geometric standard deviation of lower than about 2.0.
