摘要
用冲击波处理用共沉淀法制备的氧化铁和氧化镍混合物，合成了铁酸镍，用XRD；TEM及电子衍射法对合成产物进行了表征合成产物基本为具有较高的磁化强度的纳米级铁酸镍，主要原因可能是纳米前体有较高的的反应活性。
The nickel ferrite was prepared by shock wave treatment of coprecipitated ferric oxide and nickel oxide mixture, the product was characterized by XRD,TEM and electron difFraction. The main product consists of nanosized nickel ferrite particles and has a higher magnetization. The main reason may be that the nanosized precursor has higher reactivities and acting period of shock wave is very short, so the crystallites of nickel ferrite formed do not have enough time to grow to perfect crystallites. It was believed that the method of shock wave treatment may be a novel method for preparing nanosized powders of composite metal oxides.
