ABSTRACT:
The invention relates to a process and a device (1) for the production of spherical metal particles (2) from a melt (3). In order to produce droplets a melt jet (8) is subjected to vibrations and is led through at least one nozzle (7). In order to produce spherical metal particles (2) the droplets at the outlet of the nozzle (7) are fed to a coolant (10) for purposes of consolidation. The nozzle (7) dips into the coolant (10), the temperature of the coolant (10) being below the melting point of the melt (3).
