Title: Template-free clathrasils and clathrasil membranes

Abstract: The present invention relates to template-free clathrasils whose framework comprises essentially SiO.sub.2, wherein the crystals of the clathrasils have the platelet-like morphology of a sheet silicate. The present invention further relates to a process for preparing these template-free clathrasils and also to their use as absorbent, as seed crystals for the synthesis of clathrasil membranes of the same zeolite type and in the form of dense layers which function as gas separation membranes having a molecular sieving action.
