摘要：

Ba1-xNdxBi4Ti4O15 (BNBT) ceramics were prepared by the convention solid state reaction method. Effect of neodymium substitution on the structural and dielectric properties of the BBT ceramic was investigated. Phase structure was characterized by using X-ray diffraction analysis (XRD). A broaden dielectric peak in frequency dependent dielectric spectrum is observed during the phase transition of the BNBT ceramics. The modified Curie-Weiss and Lorentz-type relationship were used to describe the phase transition behavior. The relaxor behavior could be described well by the Lorentz-type relationship. Effect of neodymium substitution on the Curie temperatures and degree of the diffuseness in the BNBT ceramics was discussed. (C) 2016 Elsevier Ltd. All rights reserved.
