The preparation and ferroelectric properties of layered ferroelectric barium-doped SrBi2Ta2O9 were investigated in this study. Pure layered perovskites were successfully synthesized when the mixed reactants were heated up to 900°C. The formation of solid solutions of barium-doped SrBi2Ta2O9 were confirmed. The addition of barium cations was found to substantially improve the sinterability of SrBi2Ta2O9, and resulted in densified specimens at low sintering temperatures. The degree of c-axis preferred orientation of the sintered specimens also increased with the increase in the barium content in SrBi2Ta2O9. This variation in the c-axis orientation was related to the morphological change of the grains in barium-doped SrBi2Ta2O9. The barium-doped specimens exhibited well saturated P-E loops and high remanent polarization. |
