摘要：
A high silica faujasite structure, CSZ-3, has a composition 0.02 to 0.20 Cs.sub.2 O: 0.80 to 0.95 Na.sub.2 O: Al.sub.2 O.sub.3 : 5.0 to 7.0 SiO.sub.2 : 2-10 H.sub.2 O The zeolite has utility in sorption, separation and catalytic applications and it has high hydrothermal stability. It is made by reacting sources of silica, alumina, soda, and cesia together with a nucleating agent in the form of seeds or a seed solution, followed by hot aging at a temperature between 50.degree. and 160.degree. C.
