Role of content and crystal chemistry of analcime on cation exchange capacities of analcime rich rocks

, 2023
International audienceThe Abinky sedimentary formation is composed of analcimolites (i.e., rocks with more of 70 wt% of analcime) that underlies the Tchirézine 2 (Tchi2) formation, known for hosting the Imouraren uranium (U) deposit (Niger).

Synthesis and structure of analcime and analcime-zirconia composite derived from coal fly ash cenospheres [PDF]

, 2019
Cubic analcime and analcime-zirconia composite with the Si/Al ratio of 2.04 and 2.16, respectively, was synthesized by hydrothermal treatment of coal fly ash cenospheres (Si/Al = 2.7) at 150° C.

Development and characterization of clinoptilolite-, mordenite-, and analcime-based geopolymers: A comparative study

Case Studies in Construction Materials, 2021
This study examines the development of geopolymers from clinoptilolite, mordenite, and analcime and compares the properties of the resulting green-binding materials. Sodium silicate and sodium hydroxide solutions were used as activators.

Investigation of the mechanism of interaction at the hydrothermal conditions of zeolite – cubic analcime with the Li+, Mg2+, Sr2+ and Fe3+ ions

Medžiagotyra, 2013
Analcime and clinoptilolite are among the most abundant zeolites in nature. During recent decades natural analcimes and clinoptilolites, also synthetic modified analcimes have been investigated as potential and innovative substances, possible to use for ...

Hydrothermal conversion of analcime-pollucite solid solution from soil for immobilization of Cs in situand its characterization

Materials Research Express, 2021
Pollucite, considered as an ideal host material for immobilization of Cs, rarely exists in pure form but analcime-pollucite solid solution in nature due to the coexistence of Cs and Na in fact.
