| 英文摘要 | Lead-free (K0.44Na0.46)NbO3-0.5%MnO2 (KNN-0.5%MnO2) single crystals with dimensions of Phi 30 x 10 mm were successfully grown by a top seeded solution growth technique (TSSG). The X-ray diffraction pattern has shown that the as-grown crystals have an orthorhombic perovskite structure. The orthorhombic-tetragonal (TO-T.) and tetragonal-cubic phase transition temperature (the Curie temperature T-C) of the single crystal were found at 184 degrees C and 412 degrees C, respectively. The KNN-0.5%MnO2 single crystals exhibited high piezoelectric constants d(33) and dielectric permittivity epsilon(r), being 261 pC/N and 275. Well saturated P-E hysteresis loop with remnant polarization P-r=22.06 mu C/cm(2) and coercive field E-c=17.93 kV/cm was obtained at a maximum electric field of 3 kV/mm. A high strain (0.24%) and electromechanical coupling coefficient K-t (65.9%) were obtained along the (001) orientation. These excellent results indicated that the KNN-0.5%MnO2 single crystals could be used as high quality lead-free material. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved. |
