Summary:PCT No. PCT/AT96/00207 Sec. 371 Date Aug. 28, 1997 Sec. 102(e) Date Aug. 28, 1997 PCT Filed Oct. 29, 1996 PCT Pub. No. WO97/16275 PCT Pub. Date May 9, 1997The preparation of suitable powdered metal is important in powder metallurgy technology. To date, powdered metals, in particular refractory metals, have been produced using very time-consuming and, consequently, costly methods for the reduction of metallic compounds, e.g. by reducing solid metallic compounds to powdered metal in fluidized bed ovens or pusher-type furnaces. In the present invention, powdered metallic compounds are reduced by retaining the solid phase as a continuous process by particles passing through a reaction chamber to predetermined orbits. The process lasts on average 0.4 to 60 s, and the level of completeness of the process is at least 90%.
