Abstract

In this study, pure barium zirconium titanate Ba(Zr0.5Ti0.5)O3 (BZT) powders were successfully synthesized via the mechanochemical route using barium carbonate and titanium oxide as precursors. Structural properties of BZT are characterized by X-ray diffraction (XRD), Rietveld refinement, scanning electron microscope, energy dispersive X-ray spectrometry, thermogravimetric analysis, and FT-IR spectroscopy. It was observed that the ball milling operation has a significant influence on sintering temperature. Single-phase BZT was obtained under sintering conditions at 1350 °C. XRD and Rietveld refinement studies revealed that BZT composition has a cubic structure with a space group of Pm-3m (#221). As estimated by the Scherrer formula, the average crystallite size was determined as 79.2 nm for sintering temperature at 1350 °C.

高能球磨合成钛酸钡锆钡(Zr 0.5 Ti 0.5)O 3的结构研究

摘要

本研究以碳酸钡和氧化钛为前驱体,通过机械化学方法成功合成了钛酸钡钛酸钡Ba(Zr 0.5 Ti 0.5)O 3(BZT)粉末。BZT的结构特性通过X射线衍射(XRD),Rietveld精制,扫描电子显微镜,能量色散X射线光谱,热重分析和FT-IR光谱进行表征。据观察,球磨操作对烧结温度有显着影响。在1350℃的烧结条件下获得单相BZT。XRD和Rietveld精炼研究表明BZT成分具有立方结构,空间群为Pm-3m(#221)。如Scherrer公式所估计,对于1350℃的烧结温度,平均微晶尺寸确定为79.2nm。
