Abstract : Dielectric properties of 0.935(Na0.5Bi0.5)TiO3-0.065BaTiO3 lead free piezoelectric ceramic are studied. The study shows a diffuse phase transition (DPT) characterized by a frequency dispersion of permittivity which is related to cation disorder at A-site. Additionally to this dispersion, this solid solution exhibits relaxor behavior. The mechanism of relaxor behavior was discussed according to Debye, Vogel–Fulcher (V–F) and Power law models and the suitable model was predicted by means of goodness of parameter.
