Zeolites are microporous crystalline solids with well-defined structures. Generally they contain silicon, aluminium and oxygen in their framework and cations, water and/or other molecules within their pores.
Many occur naturally as minerals, and are extensively mined in many parts of the world. Others are synthetic, and are made commercially for specific uses, or produced by research scientists trying to understand more about their chemistry.

Zeolites have the ability to act as catalysts for chemical reactions which take place within the internal cavities.
Major uses are in petroleum refining and chemical process industries, ion-exchange (water softening and purification), and in the separation and removal of gases and solvents. They are often also referred to as molecular sieves.
