固相法制备α-Fe_2O_3纳米粒子

Solid-Phase Synthesis of Nanophase α-Fe_2O_3 Particle

用固相反应法合成了纳米α－Ｆｅ２Ｏ３粒子。采用ＸＲＤ、ＴＥＭ、Ｍｏｓｓｂａｕｅｒ对合成样品进行表征，结果表明此方法合成的粒子为α－Ｆｅ２Ｏ３．其粒子呈花生型，粒子直径为２０～４０ｎｍ左右．

Nanophase α-Fe2O3 particles were systhesized by a solid-phase method. The prepared samples were characterized by XRD, Mossbauer spectroscopy and TEM. The results show that the prepared samples are α-Fe2O3. The particle sizes of the samples are about 20-40nm and their shapes are peanut-like.
