determined according to the treatment effect under different conditions. The results show that the irregularly shaped metal powders are impacted into dense spherical particles, the bulk density and tap density of the metal powders increase noticeably. The combination property of metal powders is improved greatly. Key words: metal powders; particles composite system; spherical particles; powder......
of spherical Ni(OH)2 particles synthesized by the aqueous precipitation-crystallization method were investigated by SEM, TEM and XRD, and their growth mechanism was discussed. With the reaction beginning and continuing, amorphous Ni(OH)2 nano-crystallites grow up to spherical micron-particles with radially arranged crystallites. The nucleation, crystallization and re-crystallization led by Ostwald......

, as shown in Figure 2. When the reaction temperature is 10 °C, it can be observed that the morphology of the as-resulted samples mainly shows the spherical particles (Figure 2(a)), and the diameter of the particles is about 0.5-1 μm. In order to understand the detailed structure of the spherical particles, a further enlargement is shown in Figure 2(b). It could be found that some wrinkles combined......
