摘要
以ＦｅＳＯ４·７Ｈ２Ｏ和ＣＯＳＯ４·７Ｈ２Ｏ为原料，首先制备出晶粒细小的盐渍化碱式碳酸盐前驱体．在５００℃焙烧１ｈ后，制备出ＣｏＦｅ２Ｏ４纳米晶体材料，经ＸＲＤ和ＴＥＭ检测，粒径为４０ｎｍ，粒度均匀．
Nanocrystalline Coffe2O4 powders airs prepared by roasting basic carbonate precuxsor synthesized with very fine crystalline grains by using FeSO4' 7H2O and CoSO4.7H2O.The microstructure was determined by XRD and TEM analyses. The results show that thesize of the nano-paxticles was 40 um, when the precursor was roasted at 500'C for 1 h.
