Synthesis of Y2BaCuO5 Nanopowder by Co-precipitation Under Ultrasonic Irradiation

摘要：

　　Nanocrystalline Y2BaCuO5 was prepared by a co-precipitation method with aid of ultrasonic irradiation using Y2O3,CuCl2 and BaCl2 as source materials.The crystallization and morphology of the prepared nanoparticles were characterized by X-ray diffraction and transmission electron microscopy.Results showed that Y2BaCuO5 monophase can be prepared at 900℃ with NaOH + NaCO3 mixture as precipitator.Particle size of Y2BaCuO5 crystallites decreases with the increase of sonicating power.Around 30 nm Y2BaCuO5 crystallites could be achieved when sonicating power increased to 300 W.
