Abstract
Abstract (0.75-x)BiFeO3-0.25PbTiO3-xBa(Zr0.25Ti0.75)O3 (BF-PT-BZT) ternary solid solutions were prepared by the solid state reaction method. It was found from X-ray diffraction analysis that the morphotropic phase boundary (MPB) between tetragonal(T) and rhombohedral(R) phases occurred at the composition range of x from 0.13 to 0.28. For BF-PT-base ceramics, the addition of BZT can effectively decreased the tetragonality (c/a) and improved the ferroelectric as well as piezoelectric properties. The maximum value of piezoelectric constant d33 and electromechanical coupling factor kp were 182 pC/N and 0.34, respectively. Also, the ferroelectric transition temperature (Tc) of BF-PT-BZT ceramics varied in the range of 550–298 °C. It is believed that the BF-PT-BZT ternary solid solutions could be a good candidate for high-temperature applications.
