In the present work, effects of B2O3 (a flux addition) on phase transition behaviour and dielectric properties of BZT ceramics were investigated. The ceramics were prepared by a solid state sintering method. Properties of the ceramics were characterized by X-ray diffraction, electron microscopy, and dielectric measurement. The dielectric measurement showed that the ferroelectric phase transition of the ceramics became broader and phase transition temperatures increased as the amount of B2O3 increased. The results also suggested that boron ions were introduced into the lattice and altered the phase transition characteristics of the ceramics. © 2009 American Institute of Physics.
