Xrd And Tem

Nanopowder CuO was prepared by a new method which involves homogeneous precipitation in high intensity field, and powder so obtained was examined by XRD and TEM. The mechanism and effects of conditions of treatment on process and final products are also discussed. These results indicate that not only the reaction velocity was speed up dramatically under ultrasound field but also the particle size of production was greatly affected by the intensity of ultrasound field, the greater the ultrasound field, the smaller the partical size.
