Abstract
Structure and electrical properties of cerium doped bismuth barium titanate
Ba1-xCexBi8Ti7O27 (x = 0, 0.05, 0.1, 0.15, 0,2 and 0.3) ceramics were
investigated. X-ray diffraction revealed that the ceramic samples are of
single stable phase. The ceramics possess typical plate-like structure with
obvious decrease in the grain size with increasing Ce-doping amount. The
dielectric properties of the materials show relaxor behaviour. Furthermore,
the total resistance increase was observed with Ce-doping and the doped
samples show good insulation properties. The Ba0.9Ce0.1Bi8Ti7O27 ceramics
has the best piezoelectric performance (d33 = 20.6 pC/N) in contrast to that
of the undoped BaBi8Ti7O27 ceramics (d33 = 6.7 pC/N), which is substantially
enhanced piezoelectric performance of the material by more than three times.
