Abstract

Abstract: Fe doped lead zirconate titanate (PZT) ceramics are prepared by mixed-oxide route. The X-ray diffraction analysis confirms the phase formation of PZT perovskite structure. The dielectric constant and loss of the material are investigated by varying the sintering temperature and found to be 1020 and 0.002 respectively. The mechanical quality factor and piezoelectric charge coefficient for Fe doped PZT material are found to be 980 and 225 pC/N respectively. The grain size of the material is studied by using Scanning electron microscopy. These materials are used as flextensional transducers for high power low frequency SONAR applications.
