| 英文摘要 | Lead-free piezoelectric ceramics with the formula of Sr1-x(Li, Ce)(x/2)(Na0.5Bi0.5)Bi4Ti5O18 (LCSNBT-x, x = 0.0, 0.1, 0.2, 0.3, 0.4), were prepared by a conventional solid-state reaction method. X-ray diffraction analysis suggested that the substitution led to the formation of a layered perovskite structure. Plate-like morphologies were clearly observed for all the samples. The activation energy values of the ionic conductivity suggested defects were related to oxygen vacancies. The excellent electrical properties (e.g., d(33) similar to 24 pC N-1, 2P(r) similar to 15 mC cm(-2) and T-c similar to 571 degrees C) are simultaneously obtained in the ceramics with x = 0.2. Additionally, thermal annealing studies indicated that the piezoelectric constant (d(33)) of the LCSNBT-0.2 ceramic remains almost unchanged (22 pC N-1, only decreased by 8%) at temperatures below 400 degrees C, demonstrating that the ceramic is a promising candidate for high-temperature applications. |
