Rietveld Refinement of Mg1-xNix Nanoparticles Structure Synthesized by Sol-Gel technique

Abstract

By Sol-Gel technique, Mg_1-xNi_xnanoparticles (x =0, 0.05, 0.10, 0.15, 0.20, and 0.25) (NPs) were synthesized. Mg_1-xNi_x nanoparticles were prepared by using magnesium nitrate Mg (NO₃)₂ .6H₂O and citric acid C₆H₈O₇. H₂O. The nanoparticles obtained were characterized by X-ray powder diffraction (XRD), field-emitting electron microscopy (FE-SEM), and energy-dispersive X-ray spectroscopy (EDX). The crystal structure was studied by Rietveld analyzes. Grain size was also calculated by using the Scherer and Williamson-Hall equation. The lattice constant of up to 4.204 Å -4.216 Å and the grains size were obtained from the Scherrer method 14.5nm-21.5 nm and from the Williamson-Hall method 11.2 nm-14.7 nm while it was in the range of 13.5 nm-18.92 nm FESEM test.
