As heat treated BT and PLZT were characterized for phase analysis by powder X-ray diffraction, and microstructure studies by scanning electron microscopy and transmission electron microscopy. Nanocomposite thin films were characterized for room temperature dielectric, thermoelectric and ferroelectric studies. XRD patterns attested clear crystalline mixture of Bi
