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).
Claims12
A process for the production of spherical metal particles from a melt, wherein in order to produce droplets a melt jet is subjected to vibrations and is led through at least one nozzle, and wherein in order to produce the spherical metal particles the droplets at the outlet of the nozzle are fed to a liquid coolant for purposes of consolidation, and the nozzle dips into the liquid coolant, and the temperature of the coolant is below the melting point of the melt.
