“…The BSZT ceramic with 5% Zr shows the maximum d33~355 pC/N and the best kp value at 46.6%. This is consistent with its Raman and dielectric characteristics, both of which indicate a microstructure of multi-phase coexistence at room temperature [6,21,26]. In other words, by doping with Zr, we successfully created a polymorphic phase transition (PPT) region near room temperature, which has significantly enhanced the piezoelectric properties of our BST-based ceramics.…”

“…When it comes to the BSZT ceramic with 20% Zr, the A1 (TO1) and A1 (LO1) peaks, as well as the dip at ~178 cm -1 can all be observed in the -190 o C Raman spectrum. The O phase did not show a separate characteristic Raman peak due to its structure similarity with the R phase at this composition [21,22]. These two sets of characteristic peaks for the R/O and T phases shrank simultaneously in the Raman spectra collected at higher temperatures, and they almost disappeared at the same temperature, which indicates that the TPPT and TC have merged into one temperature (28 o C from the dielectric measurement).…”

In this work, we report dielectric, piezoelectric and ferroelectric properties of perovskite Ba0.95Sr0.05ZrxTi(1-x)O3 (BSZT, x=0.05, 0.10, 0.15, 0.20) ceramics synthesized by using a solid-state reaction method. It is demonstrated that when the Zr concentration was 5 at% and the sintering temperature was 1400 o C, the BSZT ceramic gives the best overall electromechanical performance, including a large remnant polarization of ~ 12.1 µC/cm 2 , large dielectric constants (εr peak ≈12600, εr RT ≈ 3500) and 1 Certain commercial equipment, instruments, or materials are identified in this paper to adequately specify the experimental procedure. Such identification does not imply recommendation or endorsement by the National Institute of Standards and Technology, nor does it imply that the materials or equipment identified are necessarily the best available for the purpose.

Since the positive influences of defects on the performance of electroceramics were discovered, investigations concerning on defects and aliovalent doping routes have grown rapidly in the fields of inorganic chemistry and condensed matter physics. In this article, we summarized the types of defects in electroceramics as well as characterization tools of defects and highlighted the effects of intrinsic and extrinsic defects on the material performances with the emphasis on dielectric, ferroelectric, and piezoelectric properties. We mainly introduced defect related theoretical simulation and experimental results in several typical incipient ferroelectrics, ferroelectrics, and antiferroelectrics. Hence, the influences of defects on the crystal lattice were summed up, and then the main physical mechanisms were highlighted. Particularly, the performance enhancements of aliovalently doped electroceramics were also evaluated and reviewed. Finally, the outlook and challenges were discussed on the basis of their current developments. This article covers not only an overview of the state-of-the-art advances of defects and aliovalent doping routes in electroceramics but also the future prospects that may open another window to tune the electrical performance of electroceramics via intentionally introducing certain defects.
