| 摘 要： | 采用添加极性与非极性添加剂优势互补的多组分复合添加方式,制造出可供亚稳相存在的空间,在极性铁离子发生"同晶替代"以及硫酸根离子"插层"的基础上,充分发挥了非极性表面活性剂对晶体形貌的"修复"作用,创建有利于所需目标产物结晶的环境相体系。在近中性环境下成功制备了晶须、片状、颗粒、荷叶状及六角形等多型态异型纳米AlOOH。用能谱图证明了添加元素的存在,用结构点阵间接印证了非极性离子的表面修复作用。 |

| Abstract: | This paper adopted a multi-component composite addition mode of adding polar and apolar additives with complementary advantages to create a space for metastable phase;on the basis of isomorphous replacement of polar iron ions and intercalation of sulfate ions,the restoration function of a polar surfactant on crystal morphology was fully exerted to establish an environment phase system for crystallizing the required target product.In the near-neutral environment,crystal-whisker,flaky,granular,patellate,hexag... |
