高纯氧化铝制备技术的进展

Progress in high-purity alumina technibues

综述了国内外高纯氧化铝的开发动向,主要介绍拜耳法、硫酸铝铵热解法、碱式碳酸铝铵热解法、有机铝水解、热解法的工艺及其应用领域。

The development of the high-pu- rity alumina at home and abroad is reviewed. Teehnologies and its applications of high- purity alumina by Bayer process,thermal de- composition of ammonium alum and ammoni- um aluminum carbonate hydroxide(AACH), hydrosis—thermo-decomposition process of organic alumina and other methods are given。
