Martensitic transformations are displacive in nature and occur in the solid state in a wide variety of metallic and non metallic materials. Although the occurrence of martensitic transformations in inorganic and ceramic compounds has been well recognized for many years, It is only in the last decade that they have achieved prominence An important group of materials in which martensitic transformations play a significant role in determining microstructure and thus properties are the perovskite-type oxides such as PbTiO(3). In this study, emphasis is given to the crystallography of the paraelectric cubic to ferroelectric tetragonal phase transformation in PbTiO(3) compound. A detailed crystallographic analysis is performed in Lead Titanate (PbTiO(3)) and the crystallographic parameters are calculated. The predictions of the crystallographic analysis are compared with the experimental results available.
