Highly oriented transparent (Sr, Ba)Nb2O6 (SBN) ceramics were prepared to obtain excellent electrooptic properties and a high spontaneous polarization, such as those observed in a Sr0.75Ba 0.25Nb2O6 (SBN75) single crystal. As a result of slip casting at a high magnetic field of 12T and firing at 1460°C for 48h in an oxygen atmosphere, highly oriented ceramics and strong ferroelectric properties were observed. The spontaneous polarization of highly oriented SBN ceramics was above 15μC/cm2, which was close to that of the SBN75 single crystal (17μC/cm2).
