Barium zirconate titanate nanoparticles synthesized by the sonochemical method

A new route for preparing barium zirconate titanate nanoparticles (BaZr0.3Ti0.7O3 (BZT)) has been developed by ultrasonication of BaCl2·2H2O, ZrOCl2·8H2O and TiCl4 precursors in a high concentration of NaOH aqueous solution. The as-prepared powders were identified by X-ray diffraction (XRD) as cubic...

Description
Summary:A new route for preparing barium zirconate titanate nanoparticles (BaZr0.3Ti0.7O3 (BZT)) has been developed by ultrasonication of BaCl2·2H2O, ZrOCl2·8H2O and TiCl4 precursors in a high concentration of NaOH aqueous solution. The as-prepared powders were identified by X-ray diffraction (XRD) as cubic perovskite BZT. The phase formation was confirmed by FT-IR and Raman spectroscopy. The increase of NaOH concentration resulted in BZT powders with smaller particle size and less BaCO3 contamination. The microstructure of BZT powders prepared in 20M NaOH examined by scanning electron microscopy (SEM) showed nanosized spherical morphology with the average particle sizes of 51±6nm.
