Abstract

The piezoelectric, dielectric, and electromechanical properties of the (KCe) co-substituted calcium bismuth niobate (CaBi2Nb 2O9, CBN) were investigated. The piezoelectric activities of CBN ceramics were significantly enhanced and the dielectric loss tan δ decreased by (KCe) substitution. The Ca0.9 (KCe) 0.05Bi2Nb2O9 ceramics possess the optimal piezoelectric properties, and the piezoelectric coefficient (d 33), Curie temperature (TC), and electromechanical coupling factors (kp and kt) were found to be 16 pC/N, 868 °C, 8.6%, and 23.8%, respectively. The excellent dielectric and electromechanical spectra, together with the high piezoelectric activities and ultrahigh Curie temperature, make CBN ceramics promising candidates for high temperature piezoelectric applications. © 2009 WILEY-VCH Verlag GmbH & Co.
