| Abstract: | The nano Ni powder was prepared by oxidation-reduction with ammonia water,Ni(NO_3)_2·6H_2O as the raw materials,the factors of surface active agent,feeding order,drying way,calcination temperature,etc. on preparation of nano Ni were discussed,and also analysed the composition, crystal structure and particle size by XRD and TEM.The experimental results showed that the samples with average size about 35 nm,the range of particle size is 30～40 nm, and the purity of nano Ni powder is high. |
