Title: Temperature dependences of the ferroelectric and dielectric properties of high curie temperature PbTiO{sub 3}–BiScO{sub 3}–Bi(Zn{sub 1/2}Zr{sub 1/2})O{sub 3}

Abstract

Highlights: ► Ceramics exhibit enhanced ferroelectric properties with the increase of temperature. ► A strong second harmonic generation effect was observed. ► Transmission electron microscopy results confirm the existence of MPB. - Abstract: The piezoelectric ceramics (1 − x − y)PbTiO{sub 3}–xBiScO{sub 3}–yBi(Zn{sub 1/2}Zr{sub 1/2})O{sub 3} exhibit greatly enhanced ferroelectric properties above room temperature, between 100 and 200 °C. A strong second harmonic generation (SHG) effect was observed below 200 °C. The highest remanent polarization (∼40 μC/cm{sup 2}) and lowest coercive field (∼10 kV/cm) were obtained at 200 °C. X-ray diffraction (XRD) analysis was used to investigate the morphotropic phase boundary (MPB) structure of (1 − x − y)PbTiO{sub 3}–xBiScO{sub 3}–yBi(Zn{sub 1/2}Zr{sub 1/2})O{sub 3} ceramics. Transmission electron microscopy (TEM) results confirm the existence of MPB, where the rhombohedral and tetragonal phases coexist. The results of thermal expansion analysis show a low thermal expansion and stability of this material. The optimal high temperature piezoelectric ceramic is obtained by the composition of 0.05BZZ–0.34BS–0.61PT.
