摘　　要：系统地介绍了超细高纯氧化铝的制备方法。作者在总结归纳的基础上,将制备方法分为三大类:气相法、液相法和多孔粗氧化铝后处理法。指出了用各种方法制得的氧化铝粉末的粒径、晶型和纯度,并比较了各类方法的优缺点。The preparation methods of ultrafine high-purity alumina are systematically presented in this paper. On the basis of summary and clasification, the methods are divided into three types--gas phase synthesis,liquid phase synthesis and the after-treatment of porous crude alumina. The particle size,crystal phase and purity quotient of alumina powder prepared by different kinds of methods are suggested. Their advantages and disadvantages are also compared.
