Crossword clues for zeolite
zeolite
The Collaborative International Dictionary
Zeolite \Ze"o*lite\, n. [Gr. ? to boil + -lite: cf. F. z['e]olithe.] (Min.) A term now used to designate any one of a family of minerals, hydrous silicates of alumina, with lime, soda, potash, or rarely baryta. Here are included natrolite, stilbite, analcime, chabazite, thomsonite, heulandite, and others. These species occur of secondary origin in the cavities of amygdaloid, basalt, and lava, also, less frequently, in granite and gneiss. So called because many of these species intumesce before the blowpipe.
Needle zeolite, needlestone; natrolite.
Wiktionary
n. (context mineralogy English) Any of several minerals, aluminosilicates of sodium, potassium, calcium or magnesium, that have a porous structure; they are used in water softeners and in ion exchange chromatography.
WordNet
n. any of a family of glassy minerals analogous to feldspar containing hydrated aluminum silicates of calcium or sodium or potassium; formed in cavities in lava flows and in plutonic rocks

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 upon rapidly heating the material stilbite, it produced large amounts of steam from water that had been adsorbed by the material. Based on this, he called the material zeolite, from the Greek , meaning "to boil" and , meaning "stone".
Zeolites occur naturally but are also produced industrially on a large scale. , 229 unique zeolite frameworks have been identified, and over 40 naturally occurring zeolite frameworks are known.
Usage examples of "zeolite".
This material was another strictly non-Mesklinite product, a piece of molecular architecture vaguely analogous to zeolite in structure, which adsorbed hydrogen on the inner walls of its structural channels and, within a wide temperature range, maintained an equilibrium partial pressure with the gas which was compatible with Mesklinite metabolic needs.
It is a common product of alteration in igneous rocks, and frequently occurs as well-developed crystals in association with zeolites lining the amygdaloidal cavities of basaltic and other rocks.
And when, in 1841, the great Charles Lyell traveled to America to give a series of lectures in Boston, sellout audiences of three thousand at a time packed into the Lowell Institute to hear his tranquilizing descriptions of marine zeolites and seismic perturbations in Campania.
The handful of wealthier islanders presented gifts of pearl necklaces, bracelets, and girdles studded with garnets, peridots, and zeolite crystals and containers covered in shagreen.
