Abstract
The production of ultrafine metal carbide powders from solid metal carbide and nitrogen-containing material is disclosed. The starting materials are fed together or separately to a plasma system where the solid metal carbide is melted and/or vaporized in the presence of nitrogen to form ultrafine metal carbide particles of high purity.
