Synthesis of Monodispersed Perovskite Barium Zirconate (BaZrO_3) by the Sonochemical Method

摘要

Barium zirconate (BaZrO_3) was synthesized successfully by the sonochemical method. The monophase of BaZrO_3 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_3 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_3 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.
