Abstract
Ultrafine particles of metals, metallic compounds, and ceramics can be produced by heating a starting material supplied hermetically with a plurality of direct current plasma currents combined at a central axis of a work coil for generating high frequency induction plasma positioned under the direct current plasma generated zone. Apparatuses used therefor are also disclosed.
