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)
