Abstract

Nickel nanopowders were synthesized using an ethylene glycol-hydrazine-ammonia (EHA) system. Based on X-ray diffraction data, the resulting powders were identified as pure crystalline nickel with an average crystal size of ∼20 nm. The mean diameter of the Ni powders decreased as the amount of hydrazine used was increased. A small amount of an AgNO3 solution, a nucleating agent, was found to facilitate the formation of the nanopowders. Ethylene glycol was found to be effective in preventing the nanopowders from becoming agglomerated.
