In this study, BaFe12O19 and BaFe12O19: Epoxy (50:50) nanocomposites were synthesized using the co-precipitation method. The structural information and material properties, such as crystallite size and electrical conductivity, were characterized by XRD, FESEM, EDX, and TEM techniques.
Herein, we synthesized BaFe12O19 and BaFe12O19: Epoxy (50:50) nanocomposite using the co-precipitation method. X-ray Diffraction (XRD) pattern confirmed the formation of hexagonal structure where the crystallite size is 27.3 nm. The Field Emission Scanning Electron Microscopy (FESEM) showed the formation of hexagonal grains and Energy Dispersive X-ray Spectroscopy (EDX) confirmed the purity of the sample. Transmission Electron Microscopy (TEM) showed the crystallite size of 34 +/- 2 nm for BaF nanoparticles and 42 +/- 2 nm for Ba-Epoxy nano composites. The values of epsilon ' is found within the range of 6.2-6 for BaF and 4.5-4 for BaF: Epoxy over the whole frequency range. In addition, the value of real part of permeability mu ' are 1.9-1.2 and 1.4-1 for BaF and BaF: Epoxy, respectively. The ac conductivity is observed to remain constant till 0.6 x 109 Hz and 0.2 x 109 Hz frequency for BaF and BaF: Epoxy, respectively.
