Abstract

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. Graphic abstract: [Figure not available: see fulltext.]
