摘要

In this study, a W-type barium ferrite nanostructure (BaFe18O27) was synthesized for the first time using a co-precipitation method without the use of any capping agents. A comprehensive characterization of the material was performed employing various analytical techniques, including Fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), scanning electron microscopy, zeta potential analysis, and diffuse reflectance spectroscopy. The XRD patterns confirmed the presence of the hexagonal phase of BaFe18O27. The average crystallite size was determined to be 51.523 nm using the Scherrer equation. The direct optical band gap of the synthesized BaFe18O27 was calculated to be 2.85 eV using Tauc’s relation. FTIR spectra revealed characteristic vibrational frequencies at 608.59 and 493.41 cm−1, corresponding to Ba–O and Fe–O stretching vibrations. Potential future applications for this material could include its use in magnetic storage devices, microwave absorbers, or as catalysts in chemical reactions due to its unique structural and electronic properties.
