ABSTRACT:
Apparatus for activation of metallic powders by subjecting the powder to bombardment with electrons, ions, or molecules in an inert or reductive atmosphere. Improved densities result in sintering, as do improved catalytic actions. Simultaneous pulverization of course particles or bodies is also achieved where desired. The pretreatment is, in some instances, combined with loading the activated particles directly into a mold, for compaction or sintering, preferably with some additional activation, all done in an integrated system.
