| 英文摘要 | Lead-free piezoelectric ceramics, (Bi1/2Na1/2)(0.935)Ba0.935Ba0.065(Fe1/2Nb1/2)(x)O-3, were prepared by the conventional solid-state reaction method. The room temperature ferroelectric P-E loops illustrated the transition of ferroelectric domains. The composition and electric field dependent strain behavior of this system were investigated. A highest unipolar strain of similar to 0.422% and corresponding normalized strain, 6'33 (=S-max/E-max) of 844 pm/V under an applied field of 50 kV/cm were observed at x = 0.020, due to the destabilization of the ferroelectric order. It is observed that the unipolar strain of BNBT-0.02FN is temperature insensitive, and the d*33 maintains a high value of similar to 600 pm/V at 90 degrees C. The observed large strain behavior can be attributed to the transformation from the ferroelectric phase at zero electric field into a relaxor ferroelectric phase under an applied electric field. The large strain response with good temperature stability would be quite suitable for environmental-friendly solid-state actuator applications. (C) 2015 Elsevier Ltd. All rights reserved. |
