Abstract: A novel method for synthesis of sodium aluminium carbonate hydroxide was studied, and the target product was obtained with aluminium sulfate as aluminium source and PEG-400 as template via the one step low heat solid state reaction.Uniform experimental design and data mining technology were applied,and the synthesis tests were made with reference to the results of data mining technology.The characterization of XRD indicated that the product was NaAl(OH)₂CO₃ with size of 4.9 nm.The composition and the particle size of the prepared sodium aluminium carbonate hydroxide were optimized in the study at the same time to get the pure nano-crystals of sodium aluminium carbonate hydroxide.

摘要： 对合成碱式碳酸钠铝的新方法进行了研究，以聚乙二醇-400（PEG-400）为模板，硫酸铝为铝源，用低热固相反应一步法成功合成得到碱式碳酸钠铝.基于均匀设计实验方案以及数据挖掘技术的应用，在数据挖掘成果的指导下进行了实验.XRD表征的结果表明，用最优工艺条件合成得到的产物为4.9 nm的NaAl(OH)₂CO₃，故同时优化控制了碱式碳酸钠铝的组成及粒度，从而得到比较纯净的碱式碳酸钠铝纳米晶体.
