| 摘 要： | 本文研究了某些碱性添加物对P_2O_5-Al_2O_3-H_2O系统水热结晶的影响。它们在一定程度上表现出结构导向作用,结晶产物依添加物之种类而变。本文还研究了Al_2O_3源、反应物组成、温度、结晶时间及高压釜内衬材质等因素的影响。实验结果表明,P_2O_5-Al_2O_3-H_2O体系的结晶行为比SiO_2-Al_2O_3-H_2O体系复杂得多,易生成多种结晶相,其中一些具有三维骨架结构。

| Abstract: | The effect of basic additives, including N, N-dimethylethanolamine, triethylamine, tetramethylethylenediamine, tetramethylamine, ethnolamine, ethylenediamine, n-hexylamine and ammonium hydroxide, on hydrothermal crystallization of P_2O_5-Al_2O_3-H_2O system has been investigated. All these additives showed structure-directing influence in some extent, but types of crystal phases formed differed with the nature of bases used. Other factors such as source of Al_2O_(?), reactant composition, temperature, crystallization period and lining material of autoclave were also observed. Experimental results indicated that crystallization processes in P_2O_5-Al_2O_3-H_2O system were much more complex than that in SiO_2-Al_2O_3-H_2O system and more varieties of crystal phases were formed among which many were crystals with porous 3-dimensional frameworks. |
