Synthesis of CuO Nano Powder

LI Yangsheng,ZHU Zhenghou,LI Fan,LAN Putian (School of Materials Science and Engineering,Nanchang University,Nanchang 330031)  
CuO nano-particles are prepared by a new method which involves homogeneous precipitation in high intensity ultrasonic field,using Cu(NO_3 )_2 and NaOH as the starting materials and pure water as the solvent.The CuO nano-particles are characterized by using techniques such as X-ray powder diffraction,transmission electron microscopy and differential thermal scan analysis,and tested by separator-size analyzer.The CuO particles with an average size of 55nm are successfully prepared.The as-prepared CuO nano-particles have regular shape,narrow size distribution and high purity.In this experiment,the mechanism and effects of conditions of treatment on the process of ultrasonic field final products are discussed.The influences of the pH values,consistency of reactant,surface-active reagent,the time and the temperature on the particles size are also discussed.How to preserve the nano-particles is significant.In this thesis,some different surface-active reagents are used.It's found the PAG-6000 has a great influence on the dispersion of nano-particles.Under the condition,there isn't any sedimentation phenomenon in 20 days.
