摘要
Lead-free perovskite (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 (BCZT) ceramics are prepared using the traditional solid-state reaction technique. Dielectric, ferroelectric and piezoelectric properties of the specimens sintered at different temperatures have been investigated. X-ray diffraction was used to understand the phase transition of the BCZT specimens. The Curie–Weiss law and the modified Curie–Weiss law were used to analyze the dielectric properties of BCZT specimens. Diffuse phase transitions are observed in BCZT specimens and the Curie–Weiss exponents are all >1.5. The dielectric permittivity versus temperature characteristics and the γ in the modified Curie–Weiss law, as a function of the dc bias field was obtained for BCZT ceramics. Piezoelectric properties have been studied and the d33 is as high as 291 pC/N.
