ZSM‐20 is a silicon‐rich analog of the faujasite‐structure, the synthesis of which is complicated. Starting from known synthesis recipes its crystallization in the system Na 2 O · Al 2 O 3 · SiO 2 · H 2 O is investigated in the presence of tetraethylammoniumhydroxyde as templating agent. The aim was to find the critical conditions for its synthesis. The synthesis products obtained are investigated by X‐ray diffraction, thermal analysis and i.r. spectroscopy.
