Synthesis and heating effect of iron/iron oxide composite and iron oxide nanoparticles [PDF]

SPIE Proceedings, 2007
Fe/Fe oxide nanoparticles, in which the core consists of metallic Fe and the shell is composed of Fe oxides, were obtained by reduction of an aqueous solution of FeCl3 within a NaBH4 solution, or, using a water-in-oil micro-emulsion with CTAB as the surfactant.
