The influence of the addition of bismuth oxide on the sintering behavior and ferroelectric properties of SrBi2Ta2O9 (SBT) ceramics has been investigated in this study. Doping excess Bi2O3 in SBT greatly enhances the densification process and changes the morphology of grains from round to plate-like shape. With the addition of Bi2O3, densified SBT is obtained after 1000°C-sintering, and its degree of c-axis orientation increases with raising the sintering temperature. The increase in the density of SBT significantly results in the increase in both of its dielectric constant and remanent polarization. However, the occurrence of preferred c-axis orientation in SBT tends to reduce its remanent polarization. |
