a type of zeolite from the analcime family was prepared by using triethanolamine, silica gel and sodium aluminate. the average particle size was around 24 µm. ftir, xrd and sem results approved the type of zeolite which was formed

Low silica zeolites are synthesized generally by sol-gel method in water. In this study, efforts were made to prepare low silica zeolites from sodium aluminate and sodium silicate, in the presence of alcohols, at 373 K under an atmospheric pressure. It was of our special interest to investigate how the addition of various alcohols into water affects the type of zeolites synthesized during cryst...
[1] The Noachian terrain west of the Isidis basin hosts a diverse collection of alteration minerals in rocks comprising varied geomorphic units within a 100,000 km region in and near the Nili Fossae. Prior investigations in this region by the Observatoire pour l’Minéralogie, l’Eau, les Glaces, et l’Activité (OMEGA) instrument on Mars Express revealed large exposures of both mafic minerals and i...
