Zeolites are widely used as ion-exchange beds in domestic and commercial water purification, softening, and other applications. In chemistry, zeolites are used to separate molecules (only molecules of certain sizes and shapes can pass through), and as traps for molecules so they can be analyzed. Zeolites are also widely used as catalysts and sorbents. Their well-defined pore structure and adjustable acidity make them highly active in a large variety of reactions.

Zeolites. Zeolites are crystalline solids structures made of silicon, aluminum and oxygen that form a framework with cavities and channels inside where cations, water and/or small molecules may reside. They are often also referred to as molecular sieves.
The mineral known as "zeolite" or "zeolites" has many different chemical elements in its composition. In general, zeolites are aluminosilicate minerals that can carry water in their crystalline structure and have the formula M2/nO.Al2O3.xSiO2.yH2O. The formula for zeolite stands in for these ratios: M can be any one of a number of metals
