Study of Dislocation Density, Porosity Effect of Synthesized Nano Ferrite Composites

Abstract:

Using Sol-Gel and impregnation processes, the GaNFe₂O₃ and GaNFe₂O₃-PPY nanocomposites were synthesized with varying concentrations of PPY 3%, 10%, and 30% by weight. Using the Sci Finder software could not trace any report in the literature for this synthesized Ga_(2x+2)NFe_2(49-x)O₃-PPY nanocomposites. The prepared gallium nitride ferrite and gallium nitride ferrite-Polypyrrole samples were subjected to structural analysis using X-ray diffraction. The X-Ray diffraction characterization confirmed Nano state formation. From the XRD spectra the dislocation density, average crystallite size, number of unit cells, and porosity were calculated and analyzed . It has been observed that with increment of unit cells and dopant concentration there is a decrease of dislocation density of gallium nitride ferrite. When the concentration of PPY is increased in gallium nitride ferrite-Polypyrrole nano composites, the dislocation density increases and the number of unit cells decreases. The porosity is increased as the concentration of PPY is increased from 3%,10% to 30% when compared to GaNFe₂O₃ nano ferrites.
