Zeolite

Ze′o-lite

,
Noun.
[Gr. [GREEK] to boil +
-lite
: cf. F.
zéolithe
.]
(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.

Webster 1828 Edition


Zeolite

ZEOLITE

,
Noun.
[Gr., to boil, to foam; stone.] A mineral, so named by Cronstedt from its intumescence before the blowpipe. Many substances have been confounded under this name, particularly such as are fusible by the blowpipe without addition, and exhibit a phosphoric brilliancy at the moment of fusion. Hauy makes two species of zeolite, which he calls mesotype and stilbite. Werner makes four subspecies, which he calls maly zeolite, fibrous zeolite, radiated zeolite, and foliated zeolite. He makes zeolite a generic name, and Jameson, who adopts this theory, arranges in this family prehnite, zeolite, apophyllite, cubicite, called by Hauy analcime, chabasite, cross-stone, laumonite, dipyre, natrolite, and wavellite. Zeolite commonly occurs in a four sided prism, terminated by a four sided pyramid; often in small fibrous masses.
