“…1(a) presents the XPRD patterns of the cobalt oxide-modified CBT piezoelectric ceramic powder sintered at 1100 • C, from bottom to top: CBT, CBT-Co4, CBT-Co10, and CBT-Co20, respectively. It can be seen that the highest intensity of diffraction peak locates at the (1 1 9) peak for all XRPD patterns, which is consistent with the fact that the most intense reflections of BLSFs are all of the type of (112m + 1) [26,27]. All the diffraction patterns are in agreement with the diffraction data for the CBT, and no secondary phase has been detected, indicating that the cobalt oxide modification does not change the crystal structure of CBT ceramics.…”

“…It is noted that the temperature (T c ) where the dielectric constant shows a maximum is found to shift to higher temperature with increasing Ca content. Such an increase in the phase transition temperature (T c ) of Cadoping bismuth layer-structured ferroelectric ceramics has been reported earlier [21,22]. The increase of transition temperature T c has a direct relationg with Goldschmidt tolerance factor (t) given by:…”

Ca x Sr 1-x Bi 2 Nb 2 O 9 , as one of Aurivillius ceramics, was prepared by a conventional solid-state reaction method. The X-ray diffraction study showed that the ceramic possess a pure structure and no secondary phase can be detected. The scanning electron microscopy indicates that the grains of all the samples are all welldefined, but no obvious impact on the size of the ceramics. The dielectric, ferroelectric and piezoelectric properties of the Ca 0.1 Sr 0.9 Bi 2 Nb 2 O 9 were investigated and found that the Curie temperature (T c ), piezoelectric constant (d 33 ), remnant polarization (2P r ) and coercive field (E c ) were about 552°C, 18 pC/N, 15.34 lC/cm 2 and 47.75 kV/cm, respectively. Meanwhile, the impedance and dielectric properties of this piezoceramic for practical applications have also been discussed.

Ferroelectric ceramics are important materials with a wide range of industrial and commercial applications. Since the discovery of the phenomenon of ferroelectricity, they have been the heart and soul of several multibillion dollar industries, ranging from highdielectric-permittivity capacitors to developments in piezoelectric transducers, pyroelectric sensors, medical diagnostic transducers, electro-optical devices, etc. Materials based on barium titanate and lead zirconate titanate have dominated the field throughout their history. Actually, the ferroelectric ceramics from the Aurivillius family receive great attention due to their large remanent polarization, lead-free nature, relatively low processing temperatures, high Curie temperatures and excellent piezoelectric properties, which made them good candidates for multiple applications. This review presents a general overview of the progress in the studies on the ferroelectric ceramics from the Aurivillius family. The progress includes several aspects: (i) structural studies, (ii) dielectric and electric behavior, (iii) piezoelectricity, and (iv) pyroelectricity.
