Synthesis and Characterization of Iron Doped Nano Barium Titanate Through Mechanochemical Route
Abstract Mechanochemical activation was used to prepare Fe doped barium titanate with intense milling in high energy planetary ball mill. Calcination was done at 1250°C for 30 min to obtain BaO, followed by milling with titania, at 400 rpm for 3 and 6 h. Ferric oxide was used for Fe doping. Annealing was done on the milled sample at 650, 750 and 850 °C for 3 and 6 h to generate stoichiometric compound of barium titanate phase. Fe doped barium titanate results in dense cluster of irregular polygonal shape morphology while morphology was spherical in nature for undoped sample. UV–VIS spectra analysis was carried out to determine bandgap (3.93 eV for undoped BT and 3.88 eV for Fe doped BT) followed by emission–excitation of the sample by fluorometric analysis.
