| 英文摘要 | Lead-free piezoelectric ceramics, Sr1-x(K0.5Bi0.5)(x)Bi2Nb2O9 (SKBN-x, x=0, 0.2, 0.5,1.0), were synthesized by a conventional solid-state reaction. Structural and electrical properties of SKBN-x ceramics were investigated. X-ray diffraction analysis suggested that the substitution led to the formation of a layered perovskite structure. Plate-like morphologies for the grains were clearly observed in all the samples, which are characteristic for layer-structure Aurivillius compounds. The Curie temperature (T-c) is found to shift to higher temperature from 445 degrees C to 509 degrees C with increasing (K, Bi) content. Excellent remanent polarization (2P(r)similar to 15 mu C/cm(2)) were obtained for SKBN-0.2 ceramic. High piezoelectric coefficient of d(33) similar to 21 pC/N were obtained for the samples at x=0.5. Additionally, thermal annealing studies indicated that the piezoelectric coefficient (d(33)) of SKBN-0.5 was unchanged even if annealing temperature increased to be 450 degrees C, demonstrating the ceramics are the promising candidates for high-temperature applications.
