Influence of High Temperature on the Crystal Structure of SrFe12O19 Nanoparticle

In this study, strontium hexaferrite nanoparticles synthesized by sol–gel autocombustion method and the effect of high annealing temperature on produced nanoparticle have been studied. Powders were annealed at 1,000 1,300°C. Structural properties powders analyzed X-ray diffraction (XRD). Hexagonal structure shape SrFe12O19 from field-emission scanning electron microscope transmission figures. Fourier-transform infrared spectroscopy confirmed formation an M-type hexagonal structure. The thermal behavior has investigated thermogravimetric analysis (TGA DTG). Height measurement with 2D 3D images surface obtained atomic force microscopy. XRD pattern was used for determining crystal examining finding lattice parameters, densities, crystallite size, specific area, strain. Crystallite strain, bulk density decreased when 1,000°C porosity area found to be increased 1,000°C. influence
