Abstract
A method for production of titanium carbide nanoparticles, the method having: a step for supplying titanium powder or titanium oxide powder into a thermal plasma flame; and a step for producing titanium carbide nanoparticles by supplying a reactive gas as a cooling gas and as a source of carbon at the downstream end of the thermal plasma flame. By varying the supplied quantity of the reactive gas, the oxygen concentration of the produced titanium carbide nanoparticles is varied. Therefore, for example, titanium carbide nanoparticles having different volume resistivity values can be produced.
