Abstract: The template grain growth technique was used to synthesis textured 60BiFeO3-PbTiO3 (60:40BFPT) by using platelets of BaTiO3 as template. Synchrotron measurement clearly showed textured 60:40BFPT. Moreover, in situ high energy synchrotron radiation was employed to investigate the influence of an external electric filed on crystallographic structure of mixed phase 60:40BFPT. Application of an electric field ¡Ý 1 kV/mm resulted in phase transformation from mixed rhombohedral/tetragonal phases (¡Ö 73.5% tetragonal / 26.5% rhombohedral) to predominately tetragonal phase (¡Ö 95%) at applied field of 6 kV/mm.
