Abstract

The Aurivillius-type bismuth layer-structured (NaBi)_0.46(LiCe) _0.04Bi₄Ti₄O₁₅ (NBT-LiCe) piezoelectric ceramics were synthesized using conventional solid-state processing. Phase analysis was performed by x-ray diffraction and microstructural morphology was assessed by scanning electron microscopy. The dielectric, piezoelectric, ferroelectric, and electromechanical properties of NBT-LiCe ceramics were investigated. The piezoelectric activities were found to be significantly enhanced compared to NBT ceramics, which can be attributed to the lattice distortion and the presence of bismuth vacancies. The dielectric and electromechanical properties of NBT-LiCe ceramics at elevated temperature were investigated in detail. The excellent piezoelectric, dielectric, and electromechanical properties, coupled with high Curie temperature (Tc =660 °C), demonstrated that the NBT-LiCe ceramics are the promising candidates for high temperature applications. © 2009 American Institute of Physics.
