摘　　要：１实验１．１样品制备在４６０Ｋ温度下真空干燥ＦｅＣ２Ｏ４·２ＨＯ１０ｈ，制得ＦｅＣ２Ｏ４；然后在Ａｒ气中升温至９２３Ｋ，保持１０ｈ；待温度下降到室温，在空气中放置４８ｈ，分解得到阳离子缺位的磁铁矿；再装入密闭无梯度反应器中，用４０ｍＬ／ｍｉｎＨ２于６...A magnetite FeC 2O 4 is prepared at high temperature 460 K by drying and vacuuming FeC 4O 4·2HO and then is transformed into an oxygen deficient magnetite through H 2 reduction.Our study shows that inner magnetic field in compounds is mainly made of infironerior magnetite Fe 3O 4+δ with A location (octahedral) and B location (tetrahedral) spectrums,α Fe and Fe δO 3.
