球形氧化铝属于氧化铝材料家族中的精细化工产品，应用领域广泛，氧化铝颗粒的球形化可极大地提高其制品的应用性能，因此球形氧化铝的制备引起了研究者的兴趣，目前，球形氧化铝的制备方法主要有均相沉淀法、溶胶-乳液-凝胶法、滴球法、模板法、气溶胶分解法和喷射法。文章力求全面评述这些制备方法的特点，并结合作者的研究结果提出新的见解。
Spherical alumina with a wide range of applications belongs to fine chemical products of the family of alumina materials.The spheroidization of alumina particles can greatly improve the application of its products,so the preparation of spherical alumina has aroused the interest of the researchers.At present,the preparation methods of spherical alumina mainly include homogeneous precipitation,sol-emulsion-gel,oil-drop,template,aerosol decomposi-tion and spray.In this paper,we try to review the characteristics of these preparation methods,and put forward some new advises combining the author′s research.
