Abstract

The 0.36(Bi(1-x)Cex)ScO3-0.64PbTiO3 (x = 0.01-0.10) ceramics were prepared by using conventional mixed oxide ceramic processing, and the effect of Ce addition on the BiScO3-PbTiO3 (BSPT) system was investigated. The results of X-ray diffraction show that lower stability of the perovskite phase is produced with the partially substitution of Ce for Bi in the BSPT ceramics, although they all still maintain tetragonal perovskite structure. Moreover, partly substituting Bi with Ce was found to shift the Curie temperature of the BSPT ceramics to lower temperature, and convert the BSPT ceramics from a classical ferroelectric to a relaxor ferroelectric.
