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]

Progressive Planet Solutions (CVE:PLAN) CEO Stephen Harpur joined Steve Darling from Proactive Investors Vancouver to discuss the company using Zeolite in cement.
He pointed out that Yemen is rich in minerals such as gold, silver, platinum, iron, zinc, lead, nickel, copper, cobalt, titanium, In addition to industrial minerals such as zeolite, limestone, gypsum, silica sand, as well as ornamental stones such as marble, basalt and other metals.
Further on, the mineralogical phase identity of the produced clay-based zeolite was studied and compared to that of a commercial zeolite.
A catalyzed HC trap-coated monolith has a bottom layer of molecular adsorbent material (aluminosilicate zeolite) for adsorbing HC emissions at ambient temperature and an overcoat of TWC to treat engine exhaust emissions when hot [6, 7, 8, 9, 10, 11, 12, 13].
THE Petroleum Technology Development Fund (PTDF), on Monday, set up a Nigeria Zeolite working group made up of representatives of the Nigerian National Petroleum Corporation (NNPC), Dangote Refinery, PTDF, Ahmadu Bello University, NCDMB and Department of Petroleum Resources (DPR) to chart a way forward for the commercialisation of Zeolite Y Catalyst.
Figure 4 depicts two scanning electron microscope (SEM) images of a typical structure of catalytic converters containing a modified zeolite. A catalyst mostly consists of a ceramic carrier material, e.g., cordierite 1, which is coated with a highly porous washcoat 2 including the catalytic active component.
There are various methods of good immobilisation, such as physical adsorption using zeolite and entrapment using [kappa]-carrageenan.
In this paper, the effect of sodium carbonate (N[a.sub.2]C[O.sub.3]) on the flexural and compressive strength of cement mortars containing natural zeolite subjected to high temperatures were examined.
The bands in the region 420-500 [cm.sup.-1] were attributed to the internal deformations of the zeolite tetrahedron [delta] O-(Si; Al)-O.
The primary zeolite structure is characterized by a framework of linked tetrahedrals composed of oxygen atoms surrounding a central cation (COOMBS et al., 1997), highlighting Al[O.sub.4] and Si[O.sub.4].
