摘要:

納米氧化鋁因具備高強度、高硬度、抗磨損、耐高溫、表面積大、吸附能力強等優異的特性，被用于航天工業、磨料、精細陶瓷、耐火材料、催化、光學材料等領域。其中，納米α-Al2O3及γ-Al2O3兩種晶型應用最為廣泛。納米氧化鋁的制備工藝也隨著研究的深入而不斷地發展。該文對制備納米α-Al2O3及γ-Al2O3粉末的傳統方法如氣相法、固相法、液相法等做了簡要介紹并分析了其各自的優缺點；針對出現的問題，結合近幾年的研究，評述了改良方法和改進工藝；簡要綜述了近年來發展出的新制備方法組合和制備原料、方法及途徑的創新，并依據部分粉體特點給予一定的應用建議，以期對今后納米氧化鋁研究者的研究工作提供一定的借鑒和啟發。

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.
