摘要： 在微波辐射条件下于混合溶剂体系中实现了AlPO4-5分子筛晶体的形貌控制. 实验结果表明, AlPO4-5分子筛晶体的长径比(c/a)随体系中乙二醇与水体积比的增大而减小, 其长径比可以在1.7~6.3之间调变. 当在体系中加入晶种诱导时, 产物晶粒的大小随加入晶种量的增加和诱导时间的延长而明显减小. 在正丁醇与水的混合体系中, 当正丁醇与水的体积比达到5∶1时, 可以形成哑铃形的特殊晶貌.

Abstract: The morphology control of AlPO4-5 crystals was achieved by microwave irradiation in mixed-solvents system. The results show that the aspect ratio of the AlPO4-5 (c/a) crystals decreases significantly with the increase of the volume ratio of EG to H2O. Interestingly, the dumbbell shaped AlPO4-5 crystals can be obtained when the volume ratio of n-butanol to H2O reaches to 5∶1 in the mixed-solvents of n-butanol and H2O. With the addition of the crystal seeds, the size of the AlPO4-5 crystals decreases with the increase of the amount of crystal seeds and the stirring time.
