Formation of Analcime Film under Hydrothermal Conditions. [PDF]

Journal of Nuclear Science and Technology, 1995
Polycrystalline analcime film was prepared from hydrogels under hydrothermal conditions. The analcime film of about 200 pm thickness built up on a porous alumina support at temperatures above 160°C, and the size and crystallinity of analcime increased with temperature.

Estimating past fluid pH and evaporative conditions in Gale crater using terrestrial analog samples from Death Valley, CA

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2531-2548, October 2026.
Abstract Boron and lithium have been observed in Ca‐sulfate veins of Gale crater. These elements are highly water mobile and can inform us regarding the aqueous processes that may have taken place in Gale crater. However, the analysis of B in Gale crater is limited to low‐Fe rocks and minerals due to spectral interference of Fe with B in ChemCam data ...

Rehydration kinetics of a natural analcime

European Journal of Mineralogy, 2010
The behavior of natural zeolites is important in any application that utilizes the gas adsorption properties of zeolites. Because of the large variety in the sizes of extraframework cavities and inter-cavity ports, the de/rehydration behavior varies considerably from zeolite to zeolite.
