Pure layered perovskites were successfully synthesized when the mixed reactants were heated up to 900¢XC. 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.journal article10.1080/105845899082156102-s2.0-0033314219https://www.scopus.com/inward/record.uri?eid=2-s2.0-0033314219&doi=10.1080%2f10584589908215610&partnerID=40&md5=325469fb2d922c48ef1f092155a2158d
