Synthesis and post-synthesis treatments
Zeolites From the synthesis to applications

From 1845 onwards, numerous researchers attempted to reproduce the synthesis of natural zeolites: chabazite (CHA), erionite (ERI), mordenite (MOR), clinoptilolite (HEU) and others. These zeolites, formed very slowly (over several hundred or thousand years) by the low-temperature reaction of volcanic ash with alkaline groundwater, are contaminated by metal compounds, quartz or other zeolites, making them difficult to use industrially. First success in the 1940s: Barrer synthesized chabazite (CHA) by reacting leucite (KAlSi ₂ O ₆ ) and analcime (NaAlSi ₂ O...
