一种纳米镍粉材料的制备方法
摘要：
一种纳米镍粉材料的制备方法,属于纳米技术领域。它的主要内容就是按照摩尔比为(1.5~2.5)∶(0.75~1)∶1的比例,取N2H4·H2O,X,NiSO4·6H2O三种原料,X是KOH或NaOH或两者的混合物,将NiSO4·6H2O配成水溶液加入N2H4·H2O,得到混合液A,再将X的混合液加入到A中,然后经洗涤、分离、干燥过程最终得到纳米镍粉。它克服了现有技术存在工艺复杂,成本复杂等缺点。本发明具有工艺简单、成本低、易操作等优点。
摘要（英）：

A process for preparing nm-class nickel powder includes such steps as proportioning N2H4.H2O, KOH or NaOH or their mixture and NiSO4.6H2O in mole ratio of (1.5-2.5):(0.75-1):1, preparing the aqueous solution of NiSO4.6H2O, adding it to N2H4.H2O, adding KOH or NaOH or their mixture to the obtained liquid mixture, washing, separation and drying to obtain the said powder finally. Its advantages are simple process, low cost, and easy operation.
