Abstract

Lead-free ceramics based on the (1 - )KNaNbO-Bi(ZnTi)O (KNN-BZT) system obtained the conventional solid-state processing technique were characterized for their crystal structure, microstructure, and electrical properties. Rietveld analysis of X-ray diffraction data confirmed the formation of a stable perovskite phase for Bi(ZnTi)O substitutions up to 30 mol%. The crystal structure was found to transform from orthorhombic 2 to cubic 3̄ through mixed rhombohedral and tetragonal phases with the increase in Bi(ZnTi)O content. Temperature-dependent dielectric behavior indicated an increase in diffuseness of both orthorhombic to tetragonal and tetragonal to cubic phase transitions as well as a gradual shift towards room temperature. The sample with ≈ 0.02 exhibited a mixed rhombohedral and orthorhombic phase at room temperature. A high-temperature X-ray diffraction study confirmed the strong temperature dependence of the phase coexistence. The sample with the composition 0.98(KNaNbO)-0.02(BiZnTiO) showed an improved room temperature piezoelectric coefficient = 109 pC/N and a high Curie temperature = 383 °C.

摘要

采用传统固态加工技术制备的基于(1 - )KNaNbO-Bi(ZnTi)O（KNN-BZT）体系的无铅陶瓷，对其晶体结构、微观结构和电学性能进行了表征。对X射线衍射数据的Rietveld分析证实，Bi(ZnTi)O替代量高达30 mol%时形成了稳定的钙钛矿相。随着Bi(ZnTi)O含量的增加，晶体结构从正交2相转变为立方3̄相，中间经过混合的菱面体相和四方相。温度依赖的介电行为表明，正交相到四方相以及四方相到立方相的转变弥散性增加，且逐渐向室温偏移。≈ 0.02的样品在室温下呈现混合的菱面体相和正交相。高温X射线衍射研究证实了相共存对温度的强烈依赖性。组成为0.98(KNaNbO)-0.02(BiZnTiO)的样品在室温下表现出改善的压电系数= 109 pC/N和较高的居里温度= 383 °C。
