- Abstract
The xBa(Ti(1−y)Zry)O3–(1−x)PbTiO3 ceramic samples with x = 0.3, y = 0.95; x = 0.3, y = 0.7; x = 0.3, y = 0.3; x = 0.3, y = 0.05; x = 0.5, y = 0.05 were synthesized by a solid state reaction technique. The XRD patterns of these samples have anisotropic broadening of diffraction peaks. The crystallographic data were analyzed by the Rietveld method. During the refinement process the Stephens's approach was used. All the samples studied are solid solutions with the tetragonal perovskite structure. The degree of tetragonal distortion of these solid solutions decreases with an increase in the Zr content. The microstructure analysis showed that the broadening of the diffraction peaks on the XRD patterns is due to both strains and small crystallite sizes.
