摘要
以FeCl3、ZnSO4·7H2O、MnSO4·H2O为原料,利用化学共沉淀法合成了锰锌铁氧体前驱体,然后对前驱体进行不同温度的热处理,并通过XRD、SEM、VSM对产物的结构、形貌、磁性能进行了表征,结果显示,在温度850℃,保温2h处理后,得到的锰锌铁氧体晶化最好,产物的晶型为立方晶系的尖晶石型,此条件下合成的锰锌铁氧体粉的比磁化饱和强度为88.97emu/g。
The Precursor of MnZn ferrite is prepared with co-precipitation method using FeCl3, ZnSO4 ·7H2O,MnSO4·H2O as raw materials. The precursor is heated at different temperatures. The structure characteristics, morphology and magnetism properties are characterized by XRD, SEM and VSM. The results show that the products heated at the temperature of 850℃ for 2 hours have the crystal form of spinel of cubic system. The products' ratio saturation magnetization is 88. 97emu/g.
