Abstract: | An organic solution of tris (acetylacetonato) iron (III) was impregnated by sorption into exfoliated graphite and dried at 180°C in air. By 1 h treatment of this precursor at 900-1200°C in Ar (heating rate to each temperature: 400 Kh-1), iron/graphite composites containing 33 mass% Fe were obtained. In these composites fine α-Fe particles of several tens to hundreds nanometers were uniformly dispersed, though the surface of some particles may be oxidized by exposure to air. For the 1000°C product, magnetization assigned for iron was 154 emu g-1, and the coercive force, Hc, 420 Oe. |
