Synthesis and Characterization of Ni SmxFe2-xO 4 Nano-Ferrites by auto combustion method
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 2
Abstract
Ni-Sm Nano ferrites with chemical formula NiSmxFe2-xo4 (x=0.00, 0.010, 0.030, 0.050, 0.070, 0.090 and 0.10) were synthesized by the citrate-gel auto combustion method. Synthesized powders are sintered at 5000C for four hours in air and characterized by XRD, SEM, EDS and FTIR. X-ray diffraction (XRD) analysis showed cubic spinel structure of the ferrites and the values of lattice parameter (a) and X-ray density (dx) increases with the increase of Sm content. Scanning electron microscope (SEM) studies revealed morphology of the Nano crystalline samples. An elemental composition of the sample was studied by Energy Dispersive spectroscopy (EDS). The FTIR spectra shows the two significant absorption bands in the wave numbers range of 370-600cm1 arising due to the inter-atomic vibrations in the tetrahedral and octahedral coordination compounds The observed results can be explained on the basis of composition
