Zeolite-Type And Nepheline Crystals In Glass-Ceramics

Zeolites are hydrated alumino-silicates. They crystallise in framework structures. Zeolites are used in the catalysis, adsorption, drying and separation technologies. Glass-ceramics are polycrystalline solids prepared by controlled crystallisation of glasses, with interesting properties. A new field of application can be opened by combination of the properties of zeolites and glass-ceramics. For example, material surfaces can be functionalized (membranes, foams) or special geometries for catalysis can be stabilised. It is possible to design glass-ceramics with a zeolite as crystal phase. In this study, further investigations of the phase distribution and the interface between the crystal phases is presented.
