以硅铝镁均匀凝胶为原料，在300℃下水热合成了一种自然界中从未发现的新型间层状蜥蜴石/皂石。结构中蜥蜴石层与皂土层的堆积比设计为3/1 ~ 1/3。这些材料根据层的组成给出部分有序的x射线衍射图。L/S= 1/1样品的晶格条纹图像显示，血小板颗粒的厚度为17.5 a，由蜥蜴石层（7.5 a）和脱水皂土层（10.0 a）组成。它们可以像蒙脱石一样分散在水中。
A novel interstratified lizardite/saponite which has never been found in nature is hydrothermally synthesized from uniform Si-Al-Mg gels at 300°C. The stacking ratios of lizardite layer to saponite layer in the structure are designed between 3/1 and 1/3. These materials give partially ordered X-ray diffraction patterns depending on the layer composition. The lattice-fringe image of the L/S= 1/1 sample shows that platelet particles have a thickness of 17.5 A consisting of a lizardite layer (7.5 A) and a dehydrated saponite layer (10.0 A). They can disperse in water like smectite.
