高纯超细α－Al_2O_3粉体制备技术的进展

Development of the Technique for Preparing Superfine α-Al_2O_3 Powder of High Purity

综述了９０年代国内高纯超细α－Ａｌ２Ｏ３粉体的生产工艺，碱式碳酸铝铵热解法，以及制备氧化铝无机分离膜方面的进展。

The developments in the technology for preparing superfine α-Al2O3 powder of high purity in nineties in our country,the process of thermo-decomposition of ammonium aluminum carbonate hydroxide(AACH),and the techniques for preparing aluminum oxide inorganic separation membrane,are reviewed in this paper.
