Synthesis and structural characterization of a novel perovskite solid solution (1-x)PbTiO₃-xBi(Zn_2/3Ta_1/3)O₃

In this work, a novel lead-reduced binary solid solution system (1-x)PbTiO₃- xBi(Zn_2/3Ta_1/3)O₃ was synthesized by the solid state reaction method. The crystal structure was analyzed by means of powder X-ray diffraction. The resulting powder X-ray diffraction patterns showed the formation of the perovskite solid solutions from x = 0 to 0.27 in a tetragonal phase symmetry. The tetragonality (c/a) of the lattice for this solid solution system was obtained from lattice parameters analysis, with the highest tetragonality value of 1.068, indicating a large crystal distortion, and suggesting a potentially high polarization, a high ferroelectric Curie temperature and a high coercive field.
