Titanium Doped Barium Ferrite—A Case Study

In this paper synthesis of titanium doped barium ferrite (BaTixFe12–xO19) nanoparticles of hexagonal structure by employing sol-gel technique is reported. The composition was varied between x = 0.25 to 0.45. Structural analysis were carried out with the help of techniques such as X-ray diffraction (XRD) for phase identification, scanning electron microscopy (SEM) for morphological studies, to identify the elemental composition energy dispersive spectroscopy (EDX) was performed and Fourier transform infrared spectroscopy (FTIR) for bonding related information. From X-ray analysis it was observed that initially, with increase in Ti concentration there was a decrease in lattice parameters and cell volume. However, at Ti concentration of 0.38, an increase in lattice parameter was observed and has been attributed to electron hopping mechanism. Morphological analysis (SEM) done on the samples reveal that the nanoparticles are spherical in shape. EDX was utilized for elemental analysis of the products. FTIR spectroscopic studies reveal prominent peaks around 470 and 540 cm−1 is attributed to formation of ferrite structure and also indicative that the reaction is complete. The obtained results were discussed in the light of the available literature.
