Beschreibung
Zusammenfassung:	A device for treating fine particles is provided which comprises a plural number of reaction chambers (2a, 2b, etc.) for providing reaction fields different from each other provided along the flow pathway on the downstream side of a nozzle (1) which jets out fine particles in a beam. The device may be provided with a chamber (2a) for a starting material for forming fine particles. The nozzle (1) may be a convergent-divergent nozzle (1).
