%X 本文以α-α-Fe<sub>2</sub>O<sub>3</sub>核，硬脂酸为模板剂，通过异丙醇铝水解，缩聚过程以及模板剂自组装合成了一种新型均一核壳结构氧化铁/氧化铝纳米球，然后通过H<sub>2</sub>/N<sub>2</sub>还原得到磁性氧化铝球。该纳米球具有均一壳层，厚度为30 nm，比表面积为140 m<sup>2</sup>/g，孔容为0.22 cm<sup>3</sup>/g，比饱和磁化强度为50.2 emu/g。<br />
Well-structured nanospheres with a magnetic core/alumina shell (MFeCA) structure were obtained by self-assembly of stearic acid/alumina species complex in 1-propanol system. The thickness of alumina uniform shell is around 30 nm. The surface area, pore volume and average pore size of the sample are 140 m<sup>2</sup>/g, 0.22 cm<sup>3</sup>/g and 5.2 nm, respectively. The saturation magnetization values of the sample are as high as 50.2 emu/g.<br />
