  • Abstract
    Acicular α-Fe nanoparticles were prepared by sodium borohydride reduction of ferrous chloride in the presence of the liquid crystalline system, C12EO4/water. The shape of the acicular particles was templated by the colloid and a magnetic field. The acicular particles obtained from the lamellar phase were 50~150 nanometers long and 5 nanometers wide. The product also included some spherical particles of 10~15 nanometers in diameter. The saturation magnetization was 94 emu/g and the coercivity was 420 Oe
