zeolite    
n. 沸石

沸石

zeolite
n 1: 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

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.
[1913 Webster]

{Needle zeolite}, needlestone; natrolite.
[1913 Webster]

  • zeolite | Structure, Properties, Applications - ACS Material
    Zeolites, which are also called molecular sieves, are crystalline microporous materials formed primarily by SiO4 and AlO4 corner-sharing tetrahedral building units that form three-dimensional (3D) frameworks with well-defined channels and cavities of molecular dimensions
  • What are Zeolites? - BYJUS
    What are Zeolites? Zeolites are microporous, three-dimensional crystalline solids of aluminium silicate Zeolites have small openings of fixed size in them which allow small molecules to pass through them easily but larger molecules cannot pass through them; that is why they are sometimes called molecular sieves

  • What is Zeolite? - Zeolite Composites
    Zeolites are aluminosilicate minerals made from interlinked tetrahedra of alumina (AlO4) and silica (SiO4) with a relatively open, three-dimensional, honeycomb like crystal structure built from the elements aluminum, oxygen, and silicon, with alkali or alkaline-Earth metals (such as sodium, potassium, and magnesium) plus water molecules trapped in the gaps between them
