| 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. |

The fine powder type materials of the nickel and cobalt typed transition metals including single metal oxide powder, elemental powder, synthetic diamond powder used as a catalyst in the field of metal alloy powder, etc., are important functional materials with special structure and properties , and are widely used in electronic information, clean energy, petrochemicals, fine ceramics and other basic industries and modern high-end defense and military fields. Nowadays, studies on the powder material are firstly focused on the development of new preparation for fine powders. Exploring preparation method for a precise chemical composition uniformity, control of ultra-fine microstructure, macroscopic nature of the outstanding fine powder to overcome the shortcomings of traditional preparation methods and to meet diverse and restrict requirements for high-performance fine powders in relevant industries, has been the long-term goal of researchers and has important theoretical and practical significance.
