Abstract

The effect of (Li,Ce) substitution for A-site on the properties of [(Na <sub>0.52</sub>K <sub>0.42</sub>Li <sub>0.06</sub>)Bi] <sub>0.5</sub>Bi <sub>2</sub> (Nb <sub>1.88</sub>Sb <sub>0.06</sub>Ta <sub>0.06</sub>)O <sub>9</sub>-based ceramics was investigated. The piezoelectric activity of [(Na <sub>0.52</sub>K <sub>0.42</sub>Li <sub>0.06</sub>)Bi] <sub>0.5</sub>Bi <sub>2</sub> (Nb <sub>1.88</sub>Sb <sub>0.06</sub>Ta <sub>0.06</sub>)O <sub>9</sub>-based ceramics is significantly improved by the modification of lithium and cerium. The Curie temperature (TC) gradually decreases from 625 to 605 °C with increasing the (Li,Ce) modification. The piezoelectric coefficient d <sub>33</sub> of the [(Na <sub>0.52</sub>K <sub>0.42</sub>Li <sub>0.06</sub>)Bi] <sub>0.44</sub>(Li,-Ce) <sub>0.03</sub>[] <sub>0.03</sub>Bi <sub>2</sub>(Nb <sub>1.88</sub>Sb <sub>0.06</sub>Ta <sub>0.06</sub>)O <sub>9</sub> ceramic was found to be 28 pC/N, the highest value among the [(Na <sub>0.52</sub>K <sub>0.42</sub>Li <sub>0.06</sub>)-Bi] <sub>0.5</sub>Bi <sub>2</sub>(Nb <sub>1.88</sub>Sb <sub>0.06</sub>Ta <sub>0.06</sub>)O <sub>9</sub>-based ceramics, also almost 50% higher than the reported d <sub>33</sub> values of other Bismuth layerstructured ferroelectric (BLSF) systems (∼5-19 pC/N). The planar coupling factor k <sub>p</sub> and k <sub>t</sub> were found to be 7.0 and 28.0%, together with the high TC (∼610 8C) and stable piezoelectric properties, demonstrating that the (Li,Ce) modified [(Na <sub>0.52</sub>K <sub>0.42</sub> Li <sub>0.06</sub>)Bi] <sub>0.5</sub>Bi <sub>2</sub>(Nb <sub>1.88</sub>Sb <sub>0.06</sub>Ta <sub>0.06</sub>)O <sub>9</sub>-based material a promising candidate for high temperature applications. © 2010 WILEY-VCH Verlag GmbH & Co.
