摘　　要：以不同牌号的硅溶胶为硅源合成L沸石,利用TEM和SEM、XRD表征技术,考察硅溶胶质量对L沸石合成的影响。结果表明:硅溶胶的粒径影响L沸石晶粒尺寸;浓度影响L合成时凝胶速度;无论何种牌号的硅溶胶在优选的配比下,均可获得较纯的L沸石。Based on different type of silica sol as the silicon source to synthesize L zeolite,using TEM and SEM,XRD characterization technology, studying the effect of silica sol quality on L zeolite synthesis.The results show that the colloidal silica particle size influence L zeolite grain size; Concentration when L synthesis gel speed; No matter what brand of silica sol, under the ratio of the optimal selection of a relatively pure L zeolite can be obtained.
