Synthesis and proposed framework topology of zeolite SUZ-4

Crystalline SUZ-4, with anhydrous composition K5Al5Si31O72, is hydrothermafly synthesized in a reaction mixture of SiO2, Al3, KOH, tetraethylammonium hydroxide and quinuclidine; its proposed framework topology is related to zeolites ferrierite and ZSM-57 and contains straight channels having apertures defined by rings of ten (Si,Al)–O species; a novel cage may as the site for non-exchangeable potassium ions.
