| 摘 要： | 本文以NH4Al（SO4）2和NH4HCO3为主要原料,采用均相沉淀法制备纳米NH4AlO（OH）HCO3（AACH）先驱体,利用X射线衍射仪和透射电镜研究了滴定方式对其制备的影响。结果表明：将碳酸氢铵溶液滴入剧烈搅拌的硫酸铝铵溶液中,可获得勃姆石,将硫酸铝铵溶液滴入剧烈搅拌的碳酸氢铵溶液中,则可获得呈纤维状的纳米NH4AlO（OH）HCO3先驱体,分散较好且无明显团聚。 |

| Abstract: | Adopting homogeneous precipitation method,nano-NH4AlO(OH)HCO3 precursor was prepared using NH4Al(SO4)2 and NH4HCO3 as the starting materials.Effects of mixing mode on preparing precursors were identified by XRD,TEM.The results indicate that mixing mode of reactants has a great influence on preparing precursors.Fibrous nano-NH4AlO(OH)HCO3(AACH) is prepared by adding an aqueous solution of NH4Al(SO4)2(AA) drop by drop to an aqueous solution of NH4HCO3(AHC).The precursor is loosely dispersed and slightly agglomerated. |
| Keywords: | NH4AlO(OH)HCO3(ACCH) precursor mixing mode nanometer |
