无机铝盐辅助活性氧化铝水热合成拟薄水铝石

采用活性氧化铝为主要原料，直接水热合成或以铝盐水解产物为晶种通过水热法制备了形貌各异的拟薄水铝石，并利用扫描电镜、X射线衍射、物理吸附仪对其表观形貌、物相结构和孔结构进行了表征。结果表明，活性氧化铝具有很强的可塑性，可直接水热合成或在晶种存在下形成棱柱状、绒球状、片状等多种形貌的拟薄水铝石，为制备形貌可控的拟薄水铝石提供了一条新的制备方法。

Inorganic aluminum salt assisted hydrothermal synthesis of pseudoboehmite by activated alumina

Pseudoboehmites with a variety of morphologies were prepared via hydrothermal method using activated alumina as main material directly or with the hydrolysis product of aluminum salt as seed crystal.The morphology，phase structure，and pore structure were characterized by scanning electron microscopy，X-ray diffraction，and physical adsorption.It was shown that the activated alumina was plastic，and can form pseudoboehmite with different morphologies，such as prismatic shape，pompon，and flake.A new method was provided for preparation of controllable morphology of pseudoboehmite.
