ABSTRACT:
A method for producing titanium particles suitable for powder metallurgy applications by atomizing a free-falling stream of molten titanium. Prior to atomization the molten titanium is maintained in a crucible lined with a solidified layer of titanium which separates the molten mass of titanium from the crucible interior to protect it against contamination. The bottom of the crucible has a nozzle through which the titanium passes to form the free-falling stream. The nozzle may be likewise lined with a layer of solidified titanium which maintains the molten titanium passing through the nozzle out of contact with the nozzle material further protecting the titanium from contamination. The free-falling stream is contacted by an inert gas jet to atomize the stream into spherical particles, which are solidified and collected.
