摘要
以Fe_3O_4粉体,Y_2O_3∶3%(摩尔分数)Eu~(3+), 5%(摩尔分数)Tb~(3+)粉体和三聚氰胺为原料,采用微波烧结法制备FeYO_3/Y_2O_3∶3%Eu~(3+), 5%Tb~(3+)复合粉体,利用X射线衍射仪(XRD)对各种粉体的结构进行分析,利用扫描电镜(SEM)对复合粉体的形貌进行观察,并利用振动样品磁强计对复合粉体的磁学性能进行测试。结果表明:复合粉体均呈针状,长度和细度均为纳米级;当Fe_3O_4,Y_2O_3∶3%Eu~(3+), 5%Tb~(3+)和三聚氰胺摩尔比为1∶3∶4时,所制备的FeYO_3/Y_2O_3∶3%Eu~(3+), 5%Tb~(3+)粉体磁力最强,饱和磁化强度为3.852 emu·g~(-1),剩余磁化强度为0.6 emu/g,矫顽力为232 Oe。
FeYO_3/Y_2O_3∶3% Eu~(3+), 5%Tb~(3+) powders were prepared by microwave sintering method using Fe_3O_4, Y_2O_3∶3%Eu~(3+), 5%Tb~(3+)and melamine powders as raw materials. The phase structure of the prepared powders was analyzed by X-ray diffractometer(XRD), and the morphology and magnetic performance of the composite powders were studied by means of scanning electron microscopy(SEM) and vibrating sample magnetometer. The results show that the composite powders are acicular, and the length and fineness are nanometer. When the molar ratio of Fe_3O_4, Y_2O_3∶3%Eu~(3+), 5%Tb~(3+) and melamine is 1∶ 3∶4, the prepared FeYO_3/Y_2O_3∶3%Eu~(3+),5%Tb~(3+) powder has the strongest magnetic force, and the saturation magnetization intensity is 3.852 emu·g~(-1), the residual magnetization intensity is 0.6 emu/g, and the coercivity is 232 Oe.
