英文摘要CaBi2Nb2O9 ceramics were fabricated via the solid-state reaction method by the addition of B2O3 as a sintering aid at lower sintering temperatures than that prepared without B2O3. Ferroelectricity, piezoelectricity, and resistivity can be still greatly enhanced when the sintering temperature is decreased from 1075 degrees C for CaBi2Nb2O9 to 975 degrees C for CaBi2Nb2O9 -0.25 wt. % B2O3. The high resistivity and weak c-axis texture ensure that the ceramics can be fully polarized in a high enough electric field. The increased spontaneous ferroelectric and remanent polarization result in a significant enhancement in the piezoelectric properties of CaBi2Nb2O9 -0.25 wt. % B2O3. The sample sintered at 975 degrees C possesses a high piezoelectric coefficient d33 of -15.0 pC/N and resistivity of 1.4 x 10(6)omega cm (at 600 degrees C) along with a high ferroelectric Curie temperature TC of -954 degrees C. This work is beneficial for the preparation of high-temperature piezoelectric ceramics with excellent electrical properties at a low sintering temperature.
