| 摘 要： | 根据穆斯堡尔谱分析,Fe3O4转变为γ-Fe2O3是γ-Fe2O3成核生长过程。根据氧化过程磁矩的变化确定Fe3O4浓度随时间的变化,-(dc)/(dt)=mc3仅在氧化初始阶段适合。

| Abstract: | The conversion of magnetite to maghemite has been studied by M?ssbauer effect. That is a nucleation and growth process of γ-Fe2O3. The change of the concentration of Fe3O4 with time was determined by the change of magnetic moment in the oxidizing process. The chemical reaction formula, -dC/dt = mC3, is only appropriate for the starting stage of the oxidizing process. |
