摘　　要：本文采用空气氧化湿法制备尖晶石型铁酸盐，得到最佳生成条件为：Ｒ＝２ＯＨ－／（Ｍ２＋＋Ｆ２＋）≥１．０；Ｍ２＋／Ｆｅ２＋＝０．５摩尔比；氧化温度３４３－３５８Ｋ；氧化时间１０－２５小时。通过ＸＲＤ、ＴＰＲ和ＴＰＤ等方法对其进行了表征。Several spinel ferrite were prepared by the wet method of air oxidation.The optimal conditions are R=2OH -/(M 2+ +Fe 2+ )≥1.0;M 2+ /Fe 2+ =0.5 moleratio,oxidation temperature of 343-358K,oxidation time of 10-25hours.Their structural characteristics and redox properties were studied by XRD、TPR and TPD.
