摘要
以ＦｅＳＯ４·７Ｈ２Ｏ和ＮｉＳＯ４·７Ｈ２Ｏ为原料，首先制备出晶粒细小的碱式碳酸盐前驱体，在３００～７００℃焙烧１ｈ后，制备出ＮｉＦｅ２Ｏ４纳米晶体材料。经ＸＲＤ和ＴＥＭ检测，粒径为３～１８ｎｍ，粒度均匀。
Nanocrystalline NiFe 2O 4 materials were prepared by roasting basic carbonate precursor with very fine crystalline grain,which is made from FeSO 4·7H 2O and NiSO 4·7H 2O at 300～700 ℃ for 1 h.The results of determination by XRD and TEM analysis show that the nano-particles is even,and the diameter is from 3 nm to 18 nm.
