Phase development and dielectric properties of (1−x)Pb(Zr0.52Ti0.48)O3–xBaTiO3 ceramics
چکیده انگلیسی

(1−x)Pb(Zr0.52Ti0.48)O3–xBaTiO3 ceramics were prepared by a modified mixed-oxide method. The phase formation was studied by XRD analysis. All compositions exhibit complete solid solutions of perovskite-like phase in the (1−x)PZT–xBT system. The (2 0 0)/(0 0 2) peak was found to split at the composition x = 0.6 and the co-existence of tetragonal–rhombohedral phases occurs with x ≤ 0.6. The possible range of compositions which correspond to a phase transition is 0.6 < x < 0.7. While pure BT ceramics exhibited a sharp phase transformation expected for normal ferroelectrics, phase transformation behavior of the (1−x)PZT–xBT solid solutions became more diffuse with increasing BT contents. This was primarily evidenced by an increased broadness in the dielectric peak, with a maximum peak width occurring at x = 0.5.
