Bismuth titanate powders were synthesized by the oxalate method. Bismuth nitrate pentahydrate and titanium (IV) isopropoxide were used as the starting precursors with a mole ratio of Bi:Ti = 4 : 3 in 0.30M oxalic acid medium. The precipitate powders were calcined between 600 and 900oC for 2 h. The structure was studied by X-ray diffraction, the morphology by scanning electron microscopy, and the elemental composition by energy dispersive X-ray spectroscopy (EDXS). Orthorhombic Bi4Ti3O12 powders were obtained after calcination at 900oC for 2h. The particles were irregular in shape and highly agglomerated with a particle size ranging from 100-300 nm. The elemental composition of Bi4Ti3O12 powders were identified by the EDXS data.
