Item type:Publication, Synthesis of monodispersed perovskite barium zirconate (BaZrO3) by the sonochemical method(2013-01-01); ; Muanghua, RangsonBarium zirconate (BaZrO<inf>3</inf>) was synthesized successfully by the sonochemical method. The monophase of BaZrO<inf>3</inf> was formed completely in short irradiation time without the calcination process. X-ray diffraction, Fourier transform and Raman spectroscopy were used to characterize formation of the perovskite BaZrO<inf>3</inf> phase, which occurs in a 60 minute single phase with a cubic crystal structure at room temperature. Therefore, sonochemical irradiation could accelerate the formation of BaZrO<inf>3</inf> particles significantly. Furthermore, scanning electron microscopy investigated the uniform shape and size. The size distribution became narrow with increasing time, as a function of irradiation. © 2013 Copyright Taylor and Francis Group, LLC. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Sonochemical synthesis of spherical BaTiO3 nanoparticles(2013-01-01); ; Monosized spherical barium titanate (BaTiO<inf>3</inf>) nanoparticles have been synthesized successfully via sonochemical reaction. The as-synthesized BaTiO<inf>3</inf> nanoparticles were characterized using X-ray diffraction of powder, Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy and transmission electron microscopy. The XRD pattern of BaTiO<inf>3</inf> particles, which were synthesized under irradiation of ultrasonic sound for 0.5 h, showed sharp diffraction peaks that corresponded to the cubic BaTiO<inf>3</inf> phase. Only a small amount of BaCO<inf>3</inf> contamination was present in the sample. The Raman active modes of the samples in this study were similar to the cubic phase of BaTiO<inf>3</inf>. The average diameter of sonochemical synthesized particles was ∼99.54 ± 18.25 nm. The synthesized BaTiO<inf>3</inf> nanoparticles were almost spherical. © 2013 Copyright Taylor and Francis Group, LLC.
