Zeolites are aluminosilicate minerals consisting of periodic arrangement of TO4 tetrahedral units, where T is an aluminum or silicon cation and O is an oxygen anion. A vast zeolite frameworks can be thought to exist of component building units, such as truncated octahedra, prisms, etc, which again are made up of vertex-linked tetrahedra with oxygen anions located at vertices. Here, we applied the novel three-dimensional weaving method to build the sphere packing models of the simplest zeolites, sodalite, by carefully chosen bead chains. Each chain comprises a chain of beads held by a pre-stressed elastic string. Spherical beads in these models represent oxygen anions; while smaller cations hidden inside the tetrahedra are not shown.
