Preparation of Y2BaCuO5 nanoparticles by a co-precipitation process with the aid of ultrasonic irradiation

Y2BaCuO5 nanocrystallites were prepared by a co-precipitation method with the aid of ultrasonic irradiation using Y2O3, CuCl2 and BaCl2 as source materials. The crystallization and morphologies of as-prepared nanoparticles were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Results show that Y2BaCuO5 monophase can be prepared at the calcining temperature up to 900 °C with NaOH and Na2CO3 mixtures as precipitator. Particle size of Y2BaCuO5 crystallites decreases with the increase of sonicating power. Around 30 nm Y2BaCuO5 crystallites can be achieved when sonicating power is increased to 300 W.
