Abstract
TiN powder was obtained by the reactive milling of a titanium powder in an air atmosphere, utilizing an attrition 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 over a period of 96 hours in the attrition mill. The XRD results indicate that a cubic TiN-like phase crystalline structure was produced in the mill, with a lattice parameter of 4.38 Å. The morphology of the obtained powders was nodular, having particle sizes within the nanometric size range.
Keywords: Attrition, Mill, Powders, Milling, TiN.
