Process for producing ultrafine particles of metals, metal compounds and ceramics and apparatus used therefor.

摘要

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 (1) combined at a central axis of a work coil (4) for generating high frequency induction plasma (2) positioned under the direct current plasma generated zone. Apparatuses used therefor are also disclosed.
