Abstract (en)
[origin: WO2005023465A1] The invention relates to a device and a method for reducing a melt stream, especially high-fusion metals or ceramics, to powder. The melt stream can be in the form of a monofil or a film and is issued by a melt nozzle supplied with melt the discharge opening of which in disposed in the area of a Laval nozzle. The melt stream is accompanied by a preferably "cold" gas flow that is accelerated by the Laval nozzle up to supersonic speed and bursts open behind the Laval nozzle. The melt nozzle is surrounded by a heat-insulation material that reaches up to the area of the Laval nozzle and substantially leaves open only the discharge opening of the melt nozzle in such a manner that the issued melt stream is shielded from the gas flow at the discharge point.
