摘　　要：就目前国内外由粉煤灰制备氧化铝(Al2O3)的方法分别从各制备工艺的特点、优点及其存在的问题等方面进行评述,并对其研究热点及其发展趋势进行了阐述。Abstract： Fly is a kind of resource containing rich alumina because of great amount of alumina oxide in it. At present, the foreign and domestic preparations of alumina oxide with fly ash are mainly acid leaching method and alkali fusion method. A brief description is given separately from their characteristic, the advantages and problems-existed and hot focus and developing trend are also discussed.
