摘要
利用XRD和TEM对无磁场和10T强磁场下低温中和法制备的试样进行了分析,结果表明:无磁场下,锰的沉淀物主要是锰的氢氧化物,而10T强磁场下,锰的沉淀物主要是30nm左右的锰的氧化物。此外,10T强磁场对锰的氧化物结晶度几乎没有影响。然后,对无磁场和10T强磁场下制备试样在无磁场中进行经不同温度(200、400和600℃)热处理2.0h后,利用XRD和SEM对热处理试样进行分析,检测结果表明,无磁场中对10T强磁场试样在600℃经热处理2.0h后,制备出了100nm左右的亚微米Mn2O3,并且其亚微米Mn2O3粒径分布很均匀。
The samples, which were prepared in zero and 10T high magnetic field by low-temperature neutralization method, were analyzed with XRD and TEM. The testing results turned out that Mn（OH）2 was prepared in zero magnetic field, and about 30nm manganese oxide was prepared in 10T high magnetic field. Besides, 10T high magnetic field has not influence on the crystal of nanometer manganese oxide. Then, the samples prepared in zero and 10T high magnetic field were prepared through heat treating at the different temperature（ 200, 400 and 600℃） for 2. Oh in zero magnetic field. The samples were analyzed with XRD and SEM. The testing results bore out that about 100nm Mn203 was prepared at 600℃ for 2. Oh in zero magnetic field with the sample prepared in 10T high magnetic field. And its grain size distribution was homogeneous.
