Abstract

Pseudobrookite (Fe2TiO5) is one of the Fe-Ti oxides that have been commonly studied. It is the most stable phase among the Fe-titanates. The multiferroic properties of Fe2TiO5 make the material can be used as a potential candidate for new applications due to the combination of semiconducting, magnetic, dielectric, and optical properties. In this research, Fe2TiO5 ceramics were synthesized using mechanical milling method for 7 h with various temperatures of 1100 °C, 1200 °C, and 1300 °C. Scanning electron microscopy (SEM) observation and x-ray diffraction (XRD) measurements were performed to analyze the microstructures and crystal structures of the Fe2TiO5 ceramics. In order to investigate the band gap of the Fe2TiO5, the UV-Vis Diffuse Reflectance measurements were conducted. It has been found that the Fe2TiO5 ceramic can be applied as a promising candidate for semiconducting devices in which the electrical conductivity and the band gap of the Fe2TiO5 ceramic were 1.73 × 10-7 Ω-1.cm-1 and 1.71 eV, respectively.
