Abstract: A process for synthesizing metal nanopowders by introducing metal carbonyl into an induction plasma torch. By taking advantage of the much lower dissolution temperature of carbonyl as opposed to the high melting temperature of conventional metal powder feeds less torch power is required. Moreover, in contrast to current powder production techniques utilizing electrode based plasma torches, the induction plasma torch does not introduce contaminants into the nanopowder.

Abstract: The invention relates to a process chamber for the selective laser fusion of material powder for the production of moulded parts. The process chamber consists of a closed chamber (1) having a bottom area, side walls and a cover area (6), a reservoir volume (3) and a production volume (2) in said bottom area, and first inlet and outlet openings (7, 9) for a protective gas. In the cover area (6), above the production volume (2), a raised region is provided with side areas, in which a beam injection window (10) is disposed that is transparent to laser radiation to be coupled in. Second inlet openings (13) are provided for a further gas in the side areas of the raised region. With the inventive design of the process chamber it is possible to protect the beam injection window (10) efficiently from being soiled by gaseous components rising from the zone of interaction, without impairment of the efficiency in guiding the protective gas.
