PURPOSE: To manufacture fine spheres of amorphous metal by a simple mechanism by melting the tip of a metallic rodlike body by the heat of arc generated between the rodlike body as an anode and a cathode, and dropping the molten metal into a cooling medium.

CONSTITUTION: Arc is generated between a metallic rodlike body 1 as an anode and a cathode 4 in gaseous Ar by means of a commercially available automatic MIG welder. When arc discharge starts, the tip of the rodlike body 1 is melted by heating, and the molten metal 2 becomes fine spheres. The spheres are accelerated by about 50W60 times the acceleration of gravity in the direction of electric current by a flow 3 of plasma generated by arc, and they drop into water in a vessel 6 through a round hole 5. The spheres are rapidly cooled, and fine spheres of amorphous metal are obtd.
