Fine metal powder materials of transition elements, such as Ni, Co, including single metal oxide powder, elementary powder, alloy powder used as catalyst in artificial diamond, are a serie of important functional material with special microstructures and properties, which, are widely used in national defense and sophisticated military industry, as well as modern key industries like electronic information, clean energy, petrochemical industy and fine ceramics. At present, most of the investigations are focused on the preparationmethods of varies new fine powders. To find out a preparationmethod to produce powders with controlled microstructure refinement, homogeneous chemical composition and outstanding macroscopic properties, is always been the aim of all the researchers, which has large theoretical value and practical significance. The method moreover, once been found out, can overcome the old ones' shortcomings and meet the high demands of variety fine powders with excellent properties. |
