AlPO_4-5分子筛转晶的研究

Studies on the Transformatin of the Crystal of AlPO_4-5 Molecular Sieves

在AlPO_4-5(3)分子筛相区内,选择几个点,探讨了温度、时间、pH等条件对AIPO_4-5分子筛合成的影响。找到了晶化过程中AIPO_4-5分子筛与其相应的磷酸铝盐间的转换关系,为合成纯净的AlPO_4基分子筛奠定了基础。

We chose some points in the phase region of the synthetic AIPO_4-5 molecular sieves to study the influence of the temperature, time, pH and other factors on the synthesis of AlPO_4-5 molecular sieves, and found the transformation relation between AIPO_4-5 molecular sieves and aluminophosphate salt in the process of the crystallization. The above results have laid the foundation of the synthesis of base molecular sieves of pure aluminophosphate.
