Abstract:	The temperature dependence of dielectric permittivity was investigated for the barium zirconium titanate solid solution system [BZT, Ba(Zr[sub x]Ti[sub 1−x])O₃ 0.25≤x≤0.5]. The dielectric relaxation behavior was observed in these ferroelectrics with diffused phase transition. In contrast to the canonical relaxors such as Pb(Mg[sub ⅓]Nb[sub ⅔])O₃, the diffused phase transition of BZT could not be well described by the popular modified Curie-Weiss law. Quasiferroelectric state theory was introduced to explain the dielectric results of the BZT relaxors.
