Abstract

Cerium-modified bismuth layer structure CaBi₂Nb ₂O₉(CBNO) ceramics were prepared by using the conventional mixed oxide method. X-ray diffraction analysis revealed that the cerium modified CBNO ceramics have a pure two-layer bismuth layer structure. The piezoelectric activity of CBNO ceramics was found significantly improved by the modification of cerium. The Curie temperature T_c, and piezoelectric coefficient d₃₃ for the CBNO ceramics with 0.50 wt% cerium modification were found to be 925°C, and 10.2 pC/N respectively. The Curie temperature gradually decreased from 940°C to 900°C with the increase of cerium modification. The dielectric spectroscopy showed that the samples possess stable piezoelectric properties, demonstrating practical potential that for high temperature applications.
