Abstract
Perovskite barium titanate synthesis was carried by modified hand-mill activated solid-state processing followed by annealing in air atmosphere with oxide precursors of barium oxide, titania at 1300 °C for 4 h after 2 h of hand-on mill activation. Phase analysis by XRD confirmed perovskite barium titanate and crystallite size estimation was observed to be about 76 nm. Homogenous growth of various agglomerates was observed, and bonding information of Ti-O, O-Ti-O stretching vibrations validates phases generated from FTIR analysis. The band gap was estimated to be about 3.38 eV from UV-VIS spectra using the Tauc formula.
