| Abstract: | In the micro-emulsion system consisting of aqueous solution, white oil, Span-80+Tween-80 and n-hexyl alcohol, the stable dispersion of nano-nickel in white oil was prepared by one-step process through reducing NiSO_4 with N2H4·H_2O. The product was characterized by XRD, TEM and disperse stability method. The results showed that the dispersions of nano-nickel with different shapes in white oil could be prepared by changing reactive condition.Among these dispersions, the disperse stability of the spherical nano-nickel dispersion in white oil was the best, whose diameter is about 13 nm. |
