Abstract
The nature of a new zeolite overgrowth has been characterized. Two overgrown samples were studied. Each sample was made up of the phases faujasite and EMT. By Rietveld refinement of the powder patterns the structure of both phases including the distribution of cations in the overgrowth was determined as well as the weight fractions of the phases in both samples. The growth of FAU crystals on the surface of EMT crystals is epitactic, as shown by HRSEM images. The epitaxial relation is [111]FAU//[001]EMT, (-110)FAU//(110)EMT. The true atomic interfacial model of the interface between faujasite and EMT is still subject of further studies.
