本文研究了掺锆对多晶铁电材料BaZrxTi1-xO3(BZT)结构和材料常数的影响。采用传统的固相反应法制备了锆钛酸钡样品。用X射线衍射仪在室温下对样品进行了表征，确定了样品为钙钛矿结构的单相。EDS研究表明，样品烧成良好，材料化学均一。剪切模数G与样品组分的关系类似于杨氏模数E的依赖关系，而泊松比ν则随着锆离子浓度的增加而减小。
In the paper the influence of zirconium admixture on the structure and material constants of polycrystalline ferroelectric materials BaZrxTi1-xO3 (BZT) was examined. The barium zirconate titanate samples were prepared by a conventional solid state reaction method. A single phase with perovskite structure of the samples, was identified by an X-Ray diffraction technique at room temperature. The performed EDS study revealed that the samples were perfectly sintered and the material was chemically homogeneous. The dependence of shear modulus G on sample composition is similar to the respective dependence of Young's modulus E, whereas the Poisson's ratio ν decreases with the increase in zirconium concentration.
