TiN powder was obtained by reaction milling of a titanium powder in air. The Ti powder was milled in an attrition mill or a Spex mill. Characterization of the powders was carried out by means of chemical analysis, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The reaction took place in 12 h in the Spex mill. It took 96 h in the attrition mill to complete the reaction. The XRD results indicate that a cubic TiN-like phase crystalline structure was produced in the two mills, with a lattice parameter of 4.38 A and 4.23 A, respectively. The morphology of the obtained powders was nodular, with particle size the nanometric size range.
