Abstract

The present invention provides a method of efficiently and stably manufacturing a high-purity metal powder of a desired particle size, which is used for powder metallurgy or the like, by generating arc 18 between electrodes 12 and 13 to melt the distal end portions of the electrodes, causing droplets 19 of the molten metal to drop onto rotating disk 14, scattering the dropped droplets by a centrifugal force, thereby cooling the droplets, and an apparatus for the same.
