中文摘要：

以铝粉、AlCl3·6H2O和水为原料，通过调整原料配比、水热反应和陈化的温度和时间，经蒸发、结晶、晶化、洗涤，制成一种组成为AlCl3·4Al（OH）3·4H2O的四水合氯化五聚铝（Al5．4H2O），采用XRD和化学分析对其进行了表徵。

英文摘要：

A novel pentanuclear polyaluninum chloride, AlCl3·4Al（OH）3·4H2O, was prepared in a hydro-thermal condition of 128℃ by using aluminum powder, AlCl3·6H2O and water as reactants, adjusting the recipe, temperature and time of reacting and aging, and evaporating, crystallizing, and washing at 98 ℃ for several times quickly. The result product was characterized by XRD and chemical analysis.
