Synthesis of monodispersed perovskite barium zirconate (BaZrO3) by the sonochemical method

Barium zirconate (BaZrO3) was synthesized successfully by the sonochemical method. The monophase of BaZrO3 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 BaZrO3 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 BaZrO3 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.
