摘要
以Al2(SO4)3·(14～18)H2O和Na2SiO3·5H2O为原料,用NaOH溶液调整凝胶体系pH,通过简单水热反应制备了一种微细粉体.粉体经X射线衍射(XRD)测试表明,含方沸石和方钠石2种沸石晶体,扫描电镜(SEM)照片显示,微细粉体为均一的直径小于5 μm的空心球.综合XRD和SEM的表征结果,所得产物为一种方沸石和方钠石共构的空心球.还探讨了该产物可能的应用领域.
A kind of fine powder was easily prepared by hydrothermal synthesis with Al_2(SO_4)_3·(14-18)H_2O and(Na_2SiO_3·5H_2O) as materials and NaOH solution as pH adjusting agent.According to the XRD test,there were two crystals of analcime and sodalite existed in the powder.And the SEM images showed that the powders were uniform hollow spheres with less 5 μm of diameter.It was concluded that the product was hollow spheres co-constructed by analcime and sodalite characterized by XRD and SEM.Finally,the possible application fields of the product are discussed.
