摘要：

Acicular alpha-Fe nanoparticles were prepared by borohydride reduction of Fe2+ in tubular lecithin reverse micellular solutions. Reduction of low concentration (0.025 or 0.05 M FeCl2) in the presence of a 1200 Oe magnetic field gave mostly spherical particles with about 20% acicular particles, The amount of acicular particles varied with reaction conditions. The acicular particles had lengths ranging from 100 to 600 nm and aspect ratios of at least 6:1.
