Abstract
Ba (Ti0.91Zr0.09) O3 ceramics doped with CuO were prepared by a solid phase reaction. The ferroelectric properties of Ba (Ti0.91Zr0.09) O3 ceramics were investigated. The results revealed that the materials are of relaxor type at Orthorhombic-Tetragonal phase transition point and undergoes a diffuse phase transition at Tetragonal-Cubic phase transition point. A non-linear P-E loop and narrow loop are observed, which exhibit a typical ferroelectric relaxor characteristic at the room temperature. Remanent polarization Pr and coercive electric field EC decrease with increasing dopant concentration, A remanent polarization of 0.20 μC/cm2 and a coercive filed of 0.81 KV/cm for BTZC38 at the room temperature were obtained.
