摘要：

Ferromagnetic alpha-Fe particles were prepared by reduction of Fe2+ by sodium borohydride in the presence of lecithin/cyclohexane/water association colloids. The particles consisted of a chains of iron spheres, 50-150 nm in diameter, held together by worm-like lecithin assemblies, about 100 nm in diameter and micrometers in length. The coercivity depended on the reaction medium and ranged from 4 to 419 Oe, with the highest coercivity particles obtained in the cyclohexane-rich region of the ternary phase diagram.
