An AFX framework type zeolite having a SiO.sub.2/Al.sub.2O.sub.3 molar ratio of greater than 50 is disclosed. The high-silica AFX framework type zeolite is synthesized from a reaction mixture having high silica and low hydroxide concentrations in the presence of an organic structure directing agent comprising 1,3-bis(1-adamantyl)imidazolium cations.

Zeolites having highly dispersed bimetallic clusters, uniformly distributed in size and composition, encapsulated therein are disclosed. Metal encapsulation and alloying is conferred by introducing ligated metal cation precursors into zeolite synthesis gels, which are subsequently crystallized hydrothermally to form zeolites with metal cations occluded in the pores. The ligated cations are anchored to the zeolite framework via siloxane bridges which enforces their uniform dispersion throughout the zeolite crystals. Treatment of the crystallized zeolites in O.sub.2 and then H.sub.2 forms bimetallic clusters, which remain narrowly distributed in size and composition.

A new family of crystalline microporous metalloalumino(gallo)phosphosilicate molecular sieves has been synthesized and are designated high charge density (HCD) MeAPSOs. These metalloalumino(gallo)phosphosilicate are represented by the empirical formula of:

R.sup.p+.sub.rA.sup.+.sub.mM.sup.2+.sub.wE.sub.xPSi.sub.yO.sub.z

where A is an alkali metal such as potassium, R is at least one quaternary ammonium cation such as ethyltrimethylammonium, M is a divalent metal such as Zn and E is a trivalent framework element such as aluminum or gallium. This family of metalloalumino(gallo)phosphosilicate materials are stabilized by combinations of alkali and quaternary ammonium cations, enabling unique, high charge density compositions. The HCD MeAPSO family of materials have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.
