Effect of Impact Milling and Ball Milling on Microstructure of Lead Titanate Powders Synthesized by Solid-State Reaction

Single phase lead titanate (PbTiO3) was prepared by solid-state route using lead (II) oxide (PbO) and titanium dioxide (TiO2) as precursors. The effects of using impact mill (IM) and ball mill (BM) in solid state reaction have been observed. X-ray diffraction (XRD) pattern was recorded at room temperature and analyzed by employing Rietveld method. X-ray diffraction (XRD) pattern shows that the PbTiO3 particles are tetragonal with tetragonality (c/a) ratio ranging from 1.058 to 1.063 and average crystallite size from 40.8 to 64.2 nm. It is found that the impact mill (IM) can be used to produce pure tetragonal perovskite with a lower tetragonality and average crystallite size.
