摘要:: 纳米氧化铝因具备高强度、高硬度、抗磨损、耐高温、表面积大、吸附能力强等优异的特性，被用于航天工业、磨料、精细陶瓷、耐火材料、催化、光学材料等领域。其中，纳米α-Al2O3及γ-Al2O3两种晶型应用最为广泛。纳米氧化铝的制备工艺也随着研究的深入而不断地发展。该文对制备纳米α-Al2O3及γ-Al2O3粉末的传统方法如气相法、固相法、液相法等做了简要介绍并分析了其各自的优缺点；针对出现的问题，结合近几年的研究，评述了改良方法和改进工艺；简要综述了近年来发展出的新制备方法组合和制备原料、方法及途径的创新，并依据部分粉体特点给予一定的应用建议，以期对今后纳米氧化铝研究者的研究工作提供一定的借鉴和启发。

Abstract:: Nano-alumina has many outstanding characteristics such as high strength, high hardness, abrasion resistance, high temperature resistance, large surface area and strong adsorption capacity, so it is widely used in space industry, abrasive materials, fine ceramics, refractory materials, catalysis materials, optical materials, etc. Among various polymorphs, α-Al2O3 and γ-Al2O3 are the most widely used. The preparation technology of Nano-aluma develops constantly with the in-depth research. In this paper, the traditional preparation methods of Nano α-alumina and γ-alumina powder, such as vapor phase method, solid phase method and liquid phase method, are introduced briefly, and their respective advantages and disadvantages are also analyzed. Aiming at problems arisen, combined with the research of recent years, improved methods and technics are reviewed. New preparation method combination and innovations on raw materials, methods and approaches are briefly summarized; some application suggestions are given based on the characteristics of the powder, so as to give some reference and inspiration to the researchers on Nano-alumina in the future.
