Nanoparticles of iron(III) oxide were synthesized by spontaneous combustion of ferrocene in ethanol solution using a simple spirit lamp. X-ray powder diffraction and electron diffraction analysis of the powder suggested the formation of gamma-Fe2O3 (Maghemite phase) having lattice constant 8.3539 +/- 0.0209 A. Transmission Electron Micrograph suggested the formation of spherical particles with an average diameter of 24.7 +/- 1.6 nm. A sextet with an isomeric shift of 0.328 mm s(-1) seen in the Mossbauer spectrum recorded at room temperature, further supports the formation of gamma-Fe2O3. The particles were dispersed freely in the polar solvents like ethanol, dimethyl sulfoxide, and water. Infra Red spectrum gave bands at 400, 432, 565, and 638 cm(-1), which confirms the presence of gamma-Fe2O3 phase.
使用简单的酒精灯，通过二茂铁在乙醇溶液中的自燃合成了三氧化二铁纳米颗粒。对该粉末进行的X射线粉末衍射和电子衍射分析表明，形成了晶格常数为8.3539 +/- 0.0209 Å的γ-Fe2O3（磁赤铁矿相）。透射电子显微镜照片表明形成了平均直径为24.7 +/- 1.6 nm的球形颗粒。在室温下记录的穆斯堡尔谱中观察到的同质异能位移为0.328 mm s(-1)的六重峰，进一步支持了γ-Fe2O3的形成。这些颗粒可自由分散在乙醇、二甲基亚砜和水等极性溶剂中。红外光谱在400、432、565和638 cm(-1)处出现谱带，这证实了γ-Fe2O3相的存在。
