【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-Al_2O_3及γ-Al_2O_3两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-Al_2O_3及γ-Al_2O_3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]:Because the nano alumina has high strength, high hardness, abrasion resistance, high temperature resistance, large surface area, strong adsorption capacity and excellent properties, has been used in aerospace industry, abrasive, fine ceramics, refractory materials, catalysis, field of optical materials. Among them, nano alpha -Al_2O_3 and gamma -Al_2O_3 two crystal is the most widely used the preparation process of nano alumina. Also with the in-depth research and development. The traditional method of preparing nano -Al_2O_3 powder on -Al_2O_3 alpha and gamma system such as gas chromatography, solid phase method, liquid phase method was briefly introduced and their advantages and disadvantages are analyzed; aiming at the existing problems, combined with the research in recent years, reviewed and improved method and process improvement; briefly summarizes the new development in recent years the preparation method of combination and preparation of raw materials, innovative methods and ways, and according to some characteristics of powder used to give advice, in order to future nano oxygen The research work of Aluminization researchers will provide some reference and inspiration.
