Zeolites are aluminosilicate minerals that are naturally employed as commercial adsorbents and impetuses. Axel Fredrik Cronstedt, a Swedish mineralogist, coined the term "zeolite" in 1756 after observing that immediately heating a substance—possibly stilbite—produced large amounts of vapour from a liquid that the substance had absorbed. Based on this, he gave the substance the name zeolite, which is derived from the Greek words zeo, which means "to boil," and lthos, which means "stone." With a better understanding of the processes involved in nucleation and crystallization, their synthesis practises are now transitioning from art to science. Zeolites made of synthetic materials are frequently used in refining procedures as well as as catalysts or carriers for a variety of chemical reactions. These remarkable substances continue to be the biggest industrial catalysts ever manufactured.
