AIP Conference Proceedings [Author(s) 1ST INTERNATIONAL CONGRESS ON SOLAR ENERGY RESEARCH, TECHNOLOGY AND APPLICATIONS (ICSERTA 2018) - Ouarzazate, Morocco (8–10 May 2018)] - Synthesis and MID-IR characterization of strontium hexaferrite nanoparticles using gel to crystallization technique

摘要： Synthesis and MID-IR characterization of strontium hexaferrite nanoparticles using gel to crystallization technique. Strontium hexaferrite (SrFe12O19) nanoparticles have been synthesized using gel to crystallization technique. Citric acid, iron nitrate and strontium nitrate were used as starting materials to prepare the gel. The prepared gel was heated at 100°C for 4 hrs in muffle furnace and sample was annealed at 800°C for 4 hrs. The prepared sample was characterized by X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. The XRD pattern confirms the formation of single phase SrFe12O19 nanoparticles. The FTIR spectrum shows the absorption bands in the range 400-600 cm-1 which are assigned to metal-oxygen vibrations. The prepared nanoparticles show the formation of single phase and can be used for various applications such as magnetic recording media, microwave devices and permanent magnets.
