Database of Zeolite Structures August 13th, 2009
The database of the Structure Commission of the International Zeolite Association provides structural information on all zeolite structure types. This includes crystallographic data and drawings for all zeolite framework types, simulated powder patterns for representative materials and relevant references.
-Descriptions and drawings of each framework type
-User-controlled animated displays of each framework type
-Crystallographic data and simulated powder diffraction patterns for representative materials
-Relevant references
-Detailed instructions for building models
-Descriptions of some families of disordered zeolite structures

Zeolites August 13th, 2009
Natural zeolites form where volcanic rocks and ash layers react with alkaline groundwater. Zeolites also crystallized in post-depositional environments over periods ranging from thousands to millions of years in shallow marine basins. Naturally occurring zeolites are rarely pure and are contaminated to varying degrees by other minerals, metals, quartz or other zeolites. For this reason, naturally occurring zeolites are excluded from many important commercial applications where uniformity and purity are essential.
