| General description: | Molecular sieves are synthetically produced zeolites (naturally occurring aluminosilicate minerals), and are characterized by pores and internal cavities of extremely uniform dimensions. These crystalline materials have three-dimensional structures based on silicon oxide (SiO4) and aluminum oxide (AlO4) polyhedra. The polyhedra are linked by their corners to produce an open structure with internal cavities in which molecules can be trapped. These materials are engineered so that access to the internal cavities is through specific and uniform sized pores.
