The effect of (Li,Ce) doping in Aurivillius phase material (Na0.52K0.42Li0.06)0.5Bi2.5(Nb1.88Sb0.06Ta0.06)O9

Journal Article


Abstract


  • The effect of (Li,Ce) substitution for A-site on the properties of [(Na 0.52K 0.42Li 0.06)Bi] 0.5Bi 2 (Nb 1.88Sb 0.06Ta 0.06)O 9-based ceramics was investigated. The piezoelectric activity of [(Na 0.52K 0.42Li 0.06)Bi] 0.5Bi 2 (Nb 1.88Sb 0.06Ta 0.06)O 9-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 33 of the [(Na 0.52K 0.42Li 0.06)Bi] 0.44(Li,-Ce) 0.03[] 0.03Bi 2(Nb 1.88Sb 0.06Ta 0.06)O 9 ceramic was found to be 28 pC/N, the highest value among the [(Na 0.52K 0.42Li 0.06)-Bi] 0.5Bi 2(Nb 1.88Sb 0.06Ta 0.06)O 9-based ceramics, also almost 50% higher than the reported d 33 values of other Bismuth layerstructured ferroelectric (BLSF) systems (∼5-19 pC/N). The planar coupling factor k p and k t 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 0.52K 0.42 Li 0.06)Bi] 0.5Bi 2(Nb 1.88Sb 0.06Ta 0.06)O 9-based material a promising candidate for high temperature applications. © 2010 WILEY-VCH Verlag GmbH & Co.
