抄録

For the development of lead-free piezoelectric ceramics, which have a tetragonal–rhombohedral morphotropic phase boundary (MPB), 0.90(Na 0.5 K 0.5 )NbO 3 – x BaZrO 3 –(0.10 - x )(Bi 0.5 Li 0.5 )TiO 3 ceramics have been synthesized by the conventional solid state reaction method. A phase diagram was summarized from the X-ray diffraction pattern and the dielectric measurements. It is found that 0.90(Na 0.5 K 0.5 )NbO 3 – x BaZrO 3 –(0.10 - x )(Bi 0.5 Li 0.5 )TiO 3 ceramics have an MPB between x = 0.07 and 0.08. In the vicinity of the MPB, it was observed that the dielectric and piezoelectric properties were enhanced.
