Synthesis and dimensionality studies for CeNi5 powder, oxidized in air at different temperatures, up to 800°C, are reported. Powder X-Ray Diffraction (XRD) and Transmission Electron Microscopy (TEM) measurements were used in order to determine resulting products morphology. The average crystalline size was obtained by X-Ray line broadening investigations from the integral breadth or the full width at half maximum (FWHM) of the diffraction profile. The approximation and decomposition of experimental X-Ray line profiles were analytically calculated using four fitting methods: Gauss, Cauchy, Voigt and Generalized Fermi Function (GFF).
