Organic structure-directing agents are necessary to the formation of defined zeolitic structures; doing without the organic component can simplfy the reaction immensely. Such a transformation, of protonated magadiite to a new layered silicate, is reported herein. The picture shows the XRD patterns of as-prepared protonated magadiite and the product after simple hydrothermal treatment at two different temparatures. After calcination (500 °C) the final material has a surface area of 457 m(2) g(-1).
有机结构导向剂对于沸石结构的形成是必要的；不使用有机成分可以极大地简化反应。本文报道了质子化镁霞石转化为新型层状硅酸盐的这一转变。图中显示了制备的质子化镁霞石和在两个不同温度下简单水热处理后的产物的 XRD 图谱。经煅烧（500°C）后，最终材料的比表面积为 457 m(2) g(-1)。
