摘要
研究了草酸铁（Ⅱ）热分解－丁醇还原法制备四氧化三铁的工艺条件，产物经ＴＥＭ、Ｓ射线衍射、Ｂ－Ｈ仪和磁天平等手段，测定了颗粒的平均粒径、物相结构和磁性能，产物随反应条件不同其平均粒径在１０００～３０００ｎｍ之间，比饱和磁化强度达１２０μＷ＿ｂ·ｍ·ｋｇ￣（－１）。
Abstract On the process condition of preparing Fe_3O_4 with heat decomposition and reduction of butanol was studied.The average diameter of particles,phase structure and magnetic properties of prod-uct were measured bv TEM,XRD,B-H andmagnetic balance. It was discovered that the av-erage diameter of product effected by reaction condition is between 1000nm and 3000nm.Ratio saturated magnetizing strength is 120μW_bm.kg￣(-1).
