ABSTRACT:
In a method wherein arcs are struck across a material to vaporize into ultra-fine particles and an electrode, thereby to manufacture the ultra-fine particles; the material to turn into the ultra-fine particles is arranged for at least either of the electrodes, and plasma currents are generated from the material and the electrode, whereby the formation rate of the ultra-fine particles per unit input is increased, and the material is formed in the shape of a rod or a wire, and a feeder capable of continuously supplying the material is disposed, whereby the ultra-fine particles can be continuously manufactured.
