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.
Any of a large group of natural hydrous aluminum silicates of sodium, calcium, potassium, barium, etc., chiefly found in cavities in igneous rocks and characterized by a ready loss or gain of water of hydration: many are capable of ion exchange with solutions.
A similar natural or synthetic silicate, used for softening water.
Any of a family of hydrous aluminum silicate minerals, whose molecules enclose cations of sodium, potassium, calcium, strontium, or barium. Zeolites are usually white or colorless, but they can also be red or yellow. They are characterized by their easy and reversible loss of water of hydration. They usually occur within cavities in basalt.
Origin of zeolite
- Swedish zeolit from Greek zein to boil (from its swelling and boiling under the blowpipe) yes- in Indo-European roots
