Sol-gel processed barium titanate (BaTiO3) ceramic has been characterized by X-ray diffraction (XRD) and Fourier Transformation Infrared (FT-IR) techniques. The results confirm that BaTiO3 crystallizes in the perovskite structure with Ba2TiO4 pyrochlore phase when calcined at relatively low temperature (800 °C) for 3h. Furthermore, XRD reveals the formation of a single-phase perovskite BaTiO3 without presence of secondary phases when calcined at the temperature of 900 and 1000°C with the following lattice parameters: a = 3.9978Å, c = 4.0197Å and a = 3.9967Å, c = 4.0220Å respectively. the calcination temperature is confirmed to has a large influence in BaTiO3 structure, several parameters including, the tetragonality, volume (V) and crystallite size were found to be increased with increasing calcination temperature.
