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.

通过 Rietveld 方法研究具有高 PbTiO3 含量的 PbTiO3–BaTiO3–BaZrO3 系统陶瓷样品的结构研究

xBa(Ti(1−是)锆是)O3个–(1−X)钛酸铅3个陶瓷样品与X= 0.3,是= 0.95；X= 0.3,是= 0.7;X= 0.3,是= 0.3;X= 0.3,是= 0.05;X= 0.5，是= 0.05 是通过固态反应技术合成的。这些样品的 XRD 图具有衍射峰的各向异性展宽。通过 Rietveld 方法分析晶体学数据。在改进过程中，使用了 Stephens 的方法。所有研究的样品都是具有四方钙钛矿结构的固溶体。这些固溶体的四方畸变程度随着Zr含量的增加而降低。微观结构分析表明，XRD 图上衍射峰的加宽是由于应变和小微晶尺寸造成的。
