A zeolite can be thought of in terms of a house, where the structure of the house (the doors, windows, walls and roof) is really the zeolite while the furniture and people are the water, ammonia and other molecules and ions that can pass in and out of the structure. The chain-like structures can be thought of like towers or high wire pylons.
Liquid dispersions of zeolite monolayers with high catalytic
The most effective approach to practical exploitation of the layered solids that often have unique valuable properties—such as graphene, clays, and other compounds—is by dispersion into colloidal suspensions of monolayers, called liquid exfoliation. This fundamentally expected behavior can be used to deposit monolayers on supports or to reassemble into hierarchical materials to produce, by ...
Heulandite: The zeolite mineral heulandite information and
Heulandite is one of the more common zeolite minerals. It has a very distinctive crystal form and has a noticeable pearly luster on cleavage surfaces. Since its original classification, Heulandite was always regarded as a single mineral species with a variable elemental makeup. In 1997, the Zeolite Subcommittee of the IMA divided this mineral into individual sub-species, thereby regarding ...

high purity zeolite 3a molecular sieve for ethanol
Zeolite 3a molecular sieve is an alkali metal alumino silicate; it is the potassium form of the Type A crystal structure. zeolite 3A has an effective pore opening of 3 angstroms (0.3 nm). It is large enough to allow in moisure, but excludes moleculars such as unsatureated hydrocarbons which can potentially form polymers: and this maximises ...

What are zeolites? | How do zeolite catalysts work?
H eat a glass of water and you'll see steam rise off it sooner or later as it comes to the boil. You certainly don't expect the same thing to happen if you heat a rock—unless it's a special kind of rock called a zeolite, which traps water inside it.Back In 1756, Swedish geologist Axel Cronstedt (1722-1765)—best known as the discoverer of nickel—coined the name "zeolite" because it ...

Zeolite - Wikipedia
Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating the material, believed to have been stilbite, produced large amounts of steam from water that had been adsorbed by the material.
Zeolite - New World Encyclopedia
Zeolites are an extremely useful group of minerals characterized by a microporous structure—that is, a structure with minute pores. Chemically, they are alumino-silicate minerals that can lose and absorb water and various ions and gases without damage to their crystal structures.
Stilbite - Wikipedia
Stilbite is the name of a series of tectosilicate minerals of the zeolite group. Prior to 1997, stilbite was recognized as a mineral species, but a reclassification in 1997 by the International Mineralogical Association changed it to a series name, with the mineral species being named: . stilbite-Ca; stilbite-Na
Zeolite Mineral Information photos and Facts, gems
Zeolite Mineral Facts: Chemical Formula: Variable for the group The group known as the zeolites comprises minerals that are hydrous silicates of aluminium with calcium, sodium, potassium, barium or strontium. The calcium compounds are commonest, followed by the sodium compounds. Compounds with the other elements are comparatively rare.

Zeolites - an overview | ScienceDirect Topics
Zeolites are a large group of aluminosilicate minerals that consist structurally of SiO4 tetrahedra arranged in ways that result in large amounts of pore space within the crystals (Figure 6). Aluminum substitutes for Si in the tetrahedral sites and, as a result, the (Si,Al)O 4 framework has a net negative charge.

The zeolite study examined 70,000 papers. "One of the challenges in learning from the literature is we publish positive examples, we publish data of things that went well," Olivetti says. In the zeolite community, researchers also publish what doesn't work. "That's a valuable dataset for us to learn from," she says.
