球形氧化铝粉体制备的研究进展

摘要/Abstract

摘要： 球形氧化铝粉体是氧化铝产品中不可缺少的一部分,因其特殊的物理化学性质而备受关注。与不规则氧化铝粉体相比,球形氧化铝粉体的形貌和尺寸能极大地提高其产品的使用性能。目前,已有大量文献探讨了制备球形氧化铝粉体的方法,但缺少文献系统性地比较不同含铝原料适用的制备方法和优缺点。本文从不同的含铝原料出发,对已有文献进行总结分析,发现不同的含铝原料决定了不同的制备方法,从而决定了工业化的难易程度,其中无规则氧化铝是球形氧化铝粉体工业化并实现量产的最佳原料。

Abstract: Spherical alumina powder is an indispensable part of alumina products and has attracted much attention due to its special physical and chemical properties. Compared with irregular alumina powder, the performance of products made of spherical alumina powder is greatly improved due to its morphology and size. At present, there is a large amount of literature discussing the method of preparing spherical alumina powder, but there is a lack of literature to systematically compare the suitable preparation methods and advantages and disadvantages of different raw materials. This paper summarizes and analyzes the existing literature from different alumina materials, and finds that different alumina materials determine different preparation methods and thereby determining the difficulty of industrialization. Among them, irregular alumina is the best raw material for industrial mass production of spherical alumina powder.

Key words: spherical alumina, metallic aluminum, aluminum salt, alcoholic aluminum, irregular alumina, preparative technique, morphology control
