中文摘要：
有可控制的粒子尺寸的好镍(Ni ) 粉末经由镍肼建筑群先锋的减小被综合纯[Ni (N2H4 ) 2 ] Cl2 和混合物[Ni (N2H4 ) 2 ] Cl2 并且[Ni (N2H4 ) 3 ] 在水的答案的 Cl2。金属性的 Ni 粉末的形成的机制由免除在复杂的镍肼和 NaOH 之间的 ligand 交换反应的肼经历镍氢氧化物的减小。与从镍盐准备 Ni 粉末的方法比较，经由镍肼建筑群先锋的减小做 Ni 粉末的方法显示出在答案为镍离子的完全的减小使用肼的半剂量的优点，并且获得的 Ni 粒子显示出更少的凝块和更好的可分散性。而且，镍粉末的平均粒子尺寸能被调整反应从 180 ～ 260 nm 控制臼齿的比率和集中。
英文摘要：
Fine nickel（Ni） powders with controllable particle sizes were synthesized via the reduction of nickel hydrazine complex precursors of pure [Ni（N2H4）2]Cl2 and a mixture of [Ni（N2H4）2]Cl2 and [Ni（N2H4）3]Cl2 in aqueous solution. The mechanism of the formation of metallic Ni powders experiences the reduction of nickel hydroxide by hydrazine released from the ligand exchange reaction between nickel hydrazine complex and NaOH. In comparison with the method of preparing Ni powders from nickel salts, the method of making Ni powders via the reduction of nickel hydrazine complex precursors shows the advantages of using half dosage of hydrazine for complete reduction of nickel ions in.solution, and the obtained Ni particles show less agglomeration and better dispersibility. Moreover, the average particle size of nickel powders can be controlled from 180 to 260 nm by adjusting the reaction molar ratio and concentration.
