| Abstract: | Ferroelectric ceramics of the system of xBiFeO3- (1-x) SrBi2Nb2O9 (SBFN) with x ranging from 0.2 were synthesized by sintering the mechanically activated mixed composition. Sintered SBFN exhibits a single-phase layered perovskite structure without detectable secondary phase. The processing temperature of SrBi2Nb2O9 decreases with increasing content of BiFeO3. |
