摘　　要：以Al2(SO4)3·(14～18)H2O和Na2SiO3·5H2O为主要原料,通过加入一类脂肪族多元醇,用NaOH溶液调整pH值,利用简单的水热法制备了几种微细粉体。经X射线衍射(XRD)测试,其中一种粉体为方沸石和方钠石晶体的复合体,扫描电镜(SEM)照片显示,微细粉体为均一的直径小于5μm的空心球;另外两种都为P型沸石,扫描电镜(SEM)照片显示为空心的八面体,大小约30μm。Taking Al_2(SO_4)_3·(14～18)H_2O and Na_2SiO_3·5H_2O as main raw materials,several kinds of fine powders were prepared by using simple hydrothermal synthesis method. The XRD tests showed that one kind of the powders was composite of analcime and sodalite, and its SEM images showed that the fine powders were uniform hollow spheres with diameter under 5 μm. The other two kinds of powders were zeolite P, and their SEM images showed that they were hollow octahedrons with diameter of around 30 μm.
