Chabazite (UK: / ˈ k æ b ə z aɪ t /) [3] is a tectosilicate mineral of the zeolite group, [4] closely related to gmelinite, with the chemical formula (Ca,K 2,Na 2,Mg)Al 2 Si 4 O 12 •6H 2 O. Recognized varieties include Chabazite-Ca, Chabazite-K, Chabazite-Na, and Chabazite-Sr, depending on the prominence of the indicated cation.

Molecules such as argon (diameter 3.84 A.) and methane (4.25 A.) are rapidly sorbed in the dehydrated zeolite; propane (width 4.9 A.) and n-butane are slowly sorbed, while iso-butane (5.6 A.) is...

This database provides structural information on all of the Zeolite Framework Types that have been approved by the Structure Commission of the International Zeolite Association (IZA-SC). It is searchable and includes:

Chabazite has a framework structure consisting of a stacked sequence of 6-rings in the order AABBCC..., forming double 6-rings at each apex of the rhombic unit cell. Thus, a type of cage (the chabazite cage) is typical of this structure (see CHA ).

Chabazite, one of the dominant zeolites in altered volcanic deposits, is the principal member of a group of zeolite minerals that have very similar modes of occurrence, chemical and physical properties, and internal structures. The group includes gmelinite, erionite, and levyne (levynite).

Chabazite zeolite (CHA) is a small pore zeolite consisting of a double 6-ring (D6R) as the basic building unit with one large ellipsoidal cavity accessed by six 8-ring windows with an aperture size of 0.38nm (Smith et al., 1963; From: Nanomaterials for Carbon Dioxide Capture and Conversion Technologies, 2023

Chabzite is very similar in structure and habit to the closely related Gmelinite. Gmelinite often forms as a pseudomorph after Chabazite, retaining the original rhombic shape but forming modified faces. The most prevalent form of Chabazite, Chabazite-Ca, is hydrous calcium aluminum silicate, and often with some sodium and potassium.
