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．
With FeSO4 · 7H2O and COSO4 · 7H2O as raw materials, firstly, a finely crystalline salinized alkali carbonate precursor was prepared. After firing at 500 ℃ for 1h, CoFe2O4 nanocrystalline materials were prepared. The particle size was 40nm and the particle size was uniform after XRD and TEM measurements.
