摘　　要：目的合成高纯相X型分子筛,并对其进行了相关表征。方法在不引入有机胺模板剂的条件下,通过水热法合成了X型分子筛;考察了反应温度、反应时间对合成X型分子筛的影响,并利用XRD,SEM等技术对所得产物进行了相关表征。结果与结论优化了X型分子筛的合成条件,最终在100℃下晶化4h,得到了相应产物;通过XRD,SEM等技术对其进行了相关表征,证明所得产物为高结晶度、高纯相的X型分子筛。该分子筛具有明显的异向生长的特点,呈现出大面积暴露(111)晶面的正八面体结构。Objective--To synthesize pure X type molecular sieves and the synthesized X type mo- lecular sieves. Methods--Without any organic templates, X type molecular sieves have been synthe- sized by hydrothermal method, of the reaction temperature and reaction time investigated of the prod- uct were systematically characterized by XRD and SEM. Results and Conclusion--The synthesis condi- tions of X type molecular sieves have been optimized. The products have been synthesized at 100 ℃ for 4h. It is confirmed that the products are pure X type molecular sieves with preferable crystallinity. Due to the anisotropic growth, the obtained X type molecular sieves mainly exhibit （111） planes.
