Abstract

The microstructure, and dielectric and piezoelectric properties of the CeO-modified potassium bismuth titanate KBi TiO (KBT) piezoelectric ceramics were investigated. X-ray diffraction analysis revealed that the cerium-modified KBT ceramics have a pure four-layer Aurivillius-type structure. The piezoelectric properties of KBT ceramics were significantly enhanced and the dielectric loss decreased by cerium doping. The Curie temperature T and piezoelectric coefficient d for the KBT ceramics with 0.50 wt% cerium modification were found to be 550°C and 28 pC/N, respectively. The Curie temperature was found to decrease gradually from 555° to 541°C with cerium modification up to 1.00 wt%. Dielectric and annealing spectroscopy showed that the materials possess stable piezoelectric properties. © 2008 The American Ceramic Society.
