FIELD: metallurgy.
SUBSTANCE: nitrogen plasma flow is generated, raw titanium-containing material and gaseous hydrocarbon are injected in the flow and mixed, steam and gas carbonitride-forming reaction mix of required composition is formed, carbonitride is condensed, force-cooled and separated from the flow. Titanium micropowder of +0.5-5 mkm size is used as titanium-containing powder material natural gas with methane content not less than 90.0 vol% is used as gaseous hydrocarbon, and they are injected together at the flow temperature not less than 5200 K, reaction products are cooled at 2800-2000 K, then passivated and coagulated by propenoic acid vapour added to the flow at molar ratio of titanium to propenoic acid 1:(0.025-0.075).
EFFECT: improved quality and increased output of titanium carbonitride nanopowder, significant reduction of free pyrolytic carbon content, powder nanoparticle protection against sirface oxidation, increased efficiency of powder entrapment in filter.
