(redirected from Zeolites)
Also found in: Thesaurus, Medical, Encyclopedia.


Any one of a family of hydrous alkali-aluminum silicate minerals, whose crystal lattice may enclose or sequester cations of sodium, potassium, magnesium, calcium, strontium, or barium, or a corresponding synthetic compound, used chiefly as molecular filters and ion-exchange agents.

[Swedish zeolit, from Greek zein, to boil (from its swelling and boiling under the blowpipe); see yes- in Indo-European roots.]


1. (Minerals) any of a large group of glassy secondary minerals consisting of hydrated aluminium silicates of calcium, sodium, or potassium: formed in cavities in lava flows and plutonic rocks
2. (Chemistry) any of a class of similar synthetic materials used in ion exchange and as selective absorbents. See molecular sieve
[c18: zeo-, from Greek zein to boil + -lite; from the swelling up that occurs under the blowpipe]
zeolitic adj


(ˈzi əˌlaɪt)

any of a group of hydrated aluminosilicate minerals, used as molecular sieves.
[1770–80; < Greek ze(în) to boil + -o- + -lite]

Summary: This study offers a long-term outlook of the zeolites market for the period between 2019 and 2029.
Zeolites are micro porous crystalline solid structures made of aluminum, silicon and oxygen that form a tetragonal framework with cavities wherein cations such as water, sulfur and other small molecules may reside.
Zeolites are microporous materials that have sub-atomic sieving and particular adsorption properties, the arrangement of a zeolite layer opens up the likelihood of working in a nonstop procedure, moreover a zeolite film would be alluring in a few applications, for example, organized reactors or sensors.
In recent years however, zeolites have been the predominant and prominent catalysts for the conversion of ethanol to hydrocarbons of relatively more value and in larger distribution than those obtained over clays [8, 9, 10].
The benefits of Pd in zeolites as low-temperature NOx catalyst or cold-start NOx absorber catalyst (PNAs) in exhaust gas have already been published [24, 25, 26, 27].
With the solvent resistant hollow fiber membrane as matrix, the membrane with zeolites @ polyimide architectures will be fabricated for the rapid binding of organic sulfur molecules.
Instead, oxides of transition metals have proven to be suitable active components in washcoats, which can either be based on metal oxides or can be incorporated into the lattice structure of alumosilicates, widely known as zeolites.
One of the pozzolans that can be used in concrete is natural zeolites that have emerged as an important binder material in recent years.
The synthesis of zeolites from ashes, generated by the combustion of oil shale [10] or coal, has become a promising way to valorize their residues.
Zeolites are defined as a mineral group characterized by a three-dimensional linked tetrahedral framework, each composed of four oxygen atoms surrounding a cation, conferring particular characteristics (COOMBS et al., 1997).
