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.
