【摘要】 三氢化铝作为一种储氢材料具有十分优异的性能，例如：储氢密度大、放氢温度低、燃烧后产物绿色无污染等诸多优点，广泛应用于航空航天以及军工领域。综述了采用“湿法”合成时产生的中间体三氢化铝缔合物以及产品α-AlH₃的物理以及化学性质对制备过程的影响。α-AlH₃的常规“湿法”合成需要分两步合成，第一步缔合物制备，介绍了几种不同醚合物的制备方法；第二步脱溶剂化转晶，脱溶剂化转晶主要分为固相甲苯法、液体甲苯法、真空法，分析了各自存在的优缺点。最后提出了一些可以改进的方向。更多还原

【Abstract】 As a hydrogen storage material, aluminum hydride has excellent properties, such as high hydrogen storage density, low hydrogen discharge temperature, and pollution-free after combustion.It is widely used in the fields of aerospace and military.In this paper, the effects of the physical and chemical properties of the intermediate aluminum hydride-etherate and product α-AlH₃,produced during the “wet method”,on the preparation process were reviewed.The conventional “wet method” synthesis of α-AlH₃ required two steps.The first step was the preparation of etherate, and several preparation methods of different etherates were introduced.The second step was desolventization and crystallization, which could be divided into solid phase toluene method, liquid toluene method and vacuum method.Finally, some directions for improvement were put forward.更多还原
