Zeolite - Wikipedia Zeolites are white solids with ordinary handling properties, like many routine aluminosilicate minerals, e g feldspar They have the general formula (MAlO2) (SiO2)x(H2O)y where M + is usually H + and Na + The Si Al ratio is variable, which provides a means to tune the properties
Zeolite | Structure, Properties, Facts | Britannica Zeolite, any member of a family of hydrated aluminosilicate minerals that contain alkali and alkaline-earth metals The zeolites are noted for their lability toward ion-exchange and reversible dehydration Learn more about the characteristics and structure of zeolites in this article
Zeolites : Minerals, Properties, Occurrence, Uses - Geology Science Zeolites, particularly sodium zeolites, are used to soften hard water by exchanging calcium and magnesium ions with sodium ions They are also employed in water treatment for the removal of heavy metals and ammonia
Zeolite - an overview | ScienceDirect Topics Zeolites are microporous solids containing pores, channels, and cages with molecular dimensions Their microporosity makes them highly suitable for catalysis, because the spaces in the lattice can be used to control access to active sites, and steric restrictions can be placed on reaction intermediates and transition states
Zeolites Statistics and Information | U. S. Geological Survey Zeolites are hydrated aluminosilicates of the alkaline and alkaline-earth metals About 40 natural zeolites have been identified during the past 200 years; the most common are analcime, chabazite, clinoptilolite, erionite, ferrierite, heulandite, laumontite, mordenite, and phillipsite
Zeolites - Chemistry Encyclopedia - structure, reaction, water, uses . . . Zeolites find wide use as ion-exchange agents, catalysts, and molecular filters in a range of industrial processes The word "zeolite" comes from the Greek for "boiling stone," because of the early observation that zeolites release water when heated
The Future of Zeolites | Chemistry of Materials Owing to their crystalline structures, zeolites have uniformly sized pores that allow molecules with specific sizes and shapes to enter, earning them the designation of molecular sieves
