用沉定法和水溶胶法制备得到了Fe_2o_3超微粒,讨论了生成物粒度与反应物浓度的关系.用扫描电镜对样品的形貌和粒度进行了测定.对样品进行了X射线衍射分析,讨论了样品的结晶情况.测量了样品的室温穆斯堡尔谱,对穆斯堡尔谱的变化进行了讨论.
The Fe 2 O 3 ultrafine particles were prepared by using the deposition method and the hydrosolysis method, and the relationship between the particle size and the reactant concentration was discussed.The morphology and particle size of the sample were determined by scanning electron microscopy.The X-ray diffraction of the sample was discussed and discussed The crystallization of the sample was measured at room temperature Mossbauer spectroscopy samples, the Mossbauer spectrum changes were discussed.
