BaBi4Ti4O15 ceramics: calcination temperature dependence of the phase formation and electrical properties

BaBi4Ti4O15 (BBT) ceramic powders were synthesized using the conventional solid-state reaction method with different calcining temperatures. Effect of the calcining temperature on the structural and electrical properties of the BBT ceramics was investigated. Phase structure of the BBT calcination powders was dependence of the calcining temperature. Results of the X-ray diffraction analyses indicated that the single phase could be obtained with the decrease in the volume of crystal cell by increasing the calcining temperature. Piezoelectric and ferroelectric properties of the BBT ceramics were significantly dependence of the calcining temperature. The maximum of piezoelectric coefficient was 23 pC/N for the ceramics with calcining temperature of 780 degrees C, together with higher Curie temperature (similar to 422 degrees C) and larger remnant polarization (similar to 4.9 mu C/cm(2)). Results for the calcining temperatures dependence of structural and electrical properties of BBT ceramics were also discussed.

Automated summary

In this study, BBT ceramic powders were synthesized with different calcining temperatures, affecting the structural and electrical properties of the ceramics. The results indicated that the calcining temperature influenced the phase structure and piezoelectric/ferroelectric properties of the BBT ceramics.
