AbstractA new zeolite overgrowth was synthesized by adding an amount of as-synthesised EMT crystals to a synthesis gel of mazzite (MAZ). After crystallisation, the overgrowth sample was made up of two major phases namely MAZ and faujasite (FAU). EMT crystals were transformed into FAU during the crystallisation process of the overgrowth sample. Bundles of needle-like crystals of mazzite overgrew faujasite particles. Weight fractions of phases in the overgrowth, the crystal structure of the phases and the distribution of cations in the overgrowth are determined. The growth of mazzite crystals onto the surface of faujasite crystals is not well oriented and a reliable epitaxial relationship between the FAU support and the overgrown material was therefore not determined.
