zeolite
[ zee-uh-lahyt ]
noun
- any of a group of hydrated silicates of aluminum with alkali metals, commonly occurring as secondary minerals in cavities in basic volcanic rocks: used for their molecular sieve properties because they undergo dehydration with little or no change in crystal structure.
zeolite
/ ˈziːəˌlaɪt; ˌziːəˈlɪtɪk /
noun
- 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
- any of a class of similar synthetic materials used in ion exchange and as selective absorbents See molecular sieve
zeolite
/ zē′ə-līt′ /
- 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.

Example Sentences
To achieve methane conversion without that input of energy, the MIT team designed a hybrid catalyst with two components: a zeolite and a naturally occurring enzyme.
The novel catalyst consists of a crystalline material called a zeolite that contains silicon, aluminum, oxygen and nickel.
These synthetic porous materials of interest to chemists specializing in selective encapsulation include such buzzwords as metal-organic frameworks, covalent organic frameworks, hydrogen-bonded organic frameworks, and zeolites.
Zeolites can become amorphous when subjected to electron beam irradiation, but that damage is related to the composition of the zeolite, and the team found that some pollucite inclusions were stable in the electron beam.
A sediment core from one of Tikal's reservoirs also found that zeolite sand had been used in its construction.
