ABSTRACT:
A new zeolite structure, CSZ-1, has a composition 0.05 to 0.55 M.sub.2 O:0.45 to 0.95 Na.sub.2 O:Al.sub.2 O.sub.3 : 3 to 7 SiO.sub.2 :x H.sub.2 O where M is cesium and/or thallium and x is 0 to 10. The zeolite has utility in sorption, separation and catalytic applications. It is made by reacting together sources of silica, alumina, soda, cesia and/or thallia, together with a nucleating agent or solution, followed by hot aging at a temperature between 50.degree. and 160.degree. C.
