| 中文摘要 | (1-x)(Na0.5K0.5)NbO3-(Bi0.5K0.5)TiO3 solid solution ceramics were successfully fabricated, exhibiting a continuous phase transition with changing x at room temperature from orthorhombic, to tetragonal, to cubic, and finally to tetragonal symmetries. A morphotropic phase boundary (MPB) between orthorhombic and tetragonal ferroelectric phases was found at 2-3 mol% (Bi0.5K0.5)TiO3 (BKT), which brings about enhanced piezoelectric and electromechanical properties of piezoelectric constant d(33) = 192 pC/N and planar electromechanical coupling coefficient k(p) = 45%. The MPB composition has a Curie temperature of 370 degrees-380 degrees C, comparable with that of the widely used PZT materials. These results demonstrate that this system is a promising lead-free piezoelectric candidate material. |
