What Are Zeolites?

Zeolities are minerals. These minerals have micro-porous structure. This term was originally derived in the 18th century by Swedish mineralogist called Axel Fredrik Cronstedt. Axel had noticed that on quickly heating a natural mineral, the stone began to bounce as water evaporated.
He applied Greek words which mean "stone that boil" and described this substance Zeolite. There are over 150 Zeolites that have been created and over 48 occur naturally. They generally are hydrated alumino-silicate minerals which basically have an "open" configuration that can contain a huge range of cations (positive ions).

Zeolities generally crystallize after they deposit in the environment over period spanning thousand to million years, these are generally found in shallow marine basins. Naturally obtained zeolites are hardly pure and are usually polluted by other minerals
