Nano-TiN particles were prepared by using the hydrogen plasma-metal reaction method in a mixture of H 2 and N 2, using titanium metal as starting material. The structure of nano-TiN particles were characterized by X-ray diffraction system (XRD). The morphology and mean particle size were determined by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The element content was studied by Energy X-ray microanalysis system (EDS). The thermal stability of nano-TiN particles was investigated by thermal analysis system (TG-DSC). It is showed that nano-TiN particles can be produced by hydrogen plasma-metal reaction method. The particles have uniform diameters, cubic shape, high purity, good dispersibility and high thermal stability.
