Abstract

Abstract The microstructure, dielectric and pyroelectric properties of pure and Gd3+- doped barium zirconium titanate in the form of Ba(Zr0.52Ti0.48)O3 and (Ba1-xGdx)(Zr0.52Ti0.48)O3 (x = 0.1 and 0.2) were studied in this work. These ceramics were synthesized from solid state reaction method at 1050 °C. The patterns obtained from x-ray diffraction revealed the formation of perovskite phase with tetragonal crystal symmetry. As the concentration of Gd-ion increased, the value of temperature dependent dielectric constant varied whereas the Curie temperature of the ceramics shifted towards higher temperature side. The ceramic sample doped with Gd = 0.1 exhibited diffuse phase transition whereas other one showed relaxor like behavior. This result is attributed to unsystematic decrease in average grain size due to doping of Gd-ions. The temperature dependent pyroelectric current was negative at ∼150 °C for pure ceramics and at ∼200 °C for Gd-doped ceramics. This negative pyroelectric current represents the primary pyroelectric effect within that temperature.

钆对Ba(Zr0.52Ti0.48)O3陶瓷介电和热释电行为的影响
本文研究了纯钛酸锆钡和掺杂Gd3+的钛酸锆钡的微观结构、介电和热释电性能,分别为Ba(Zr0.52Ti0.48)O3和(Ba1-xGdx)(Zr0.52Ti0.48)O3 (x = 0.1和0.2)。采用固相反应法在1050℃下合成了这些陶瓷。x射线衍射图显示钙钛矿相的形成具有四方晶体对称性。随着gd离子浓度的增加,陶瓷的介电常数随温度的变化而变化,而居里温度则向高温侧移动。Gd = 0.1掺杂的陶瓷样品表现为扩散相变,而另一种样品表现为类弛豫相变。这一结果归因于gd离子掺杂导致的平均晶粒尺寸的非系统减小。纯陶瓷在~ 150°C时,热释电电流为负,而掺杂gd的陶瓷在~ 200°C时,热释电电流为负。这个负热释电电流表示在该温度内的初级热释电效应。

期刊介绍: Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals. Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
