    Abstract:

    The Aurivillius-type bismuth layer-structure Sr0.84(LiHo)0.08Bi4Ti4O15 (SBT-LiHo) piezoelectric ceramics were synthesized using conventional solid state processing. Phase analysis was performed by X-ray diffraction (XRD). The dielectric, piezoelectric, ferroelectric, and electromechanical properties of SBT-LiHo ceramics were investigated. The piezoelectric activities were found to be significantly enhanced compared to SrBi4Ti4O15 (SBT) ceramics, which can be attributed to the lattice distortion and the presence of bismuth vacancies. The dielectric properties of SBT-LiHo ceramics at elevated temperatures were investigated in detail.
