Abstract

PURPOSE:To efficiently produce powder having the desired particle size by arranging end parts of pair of electrodes as facing in an inclined downward direction to hold stability of arc even under high pressure atmosphere and scattering after surely dropping all drips of molten metal on a disk. CONSTITUTION:The arc 75 between the electrodes 73 arranging the end thereof as facing in the inclined downward direction is generated and the drip 76 produced by melting the electrodes 73 with this arc 75 is dropped on the disk 78 rotating at high speed. In the drip 76, electromagnetic pinch force generating by facing the electrodes 73 in the inclined downward direction is worked and even in case the atmospheric pressure is high, all drips 76 are surely dropped on the disk 78 and by scattering after colliding against projected side wall 78a, the scattering condition is stabilized and the powder having the desired particle size can be obtd. Further, the electrode 73 is bar-like and is desirable to provide a rotating device 81 for rotating around the axis thereof.
