Zeolites (picture source: www.answers.com)
Zeolites are natural volcanic minerals with a number of unique characteristics. Zeolites were formed when volcanic ash was deposited in ancient alkaline lakes. The interaction of the volcanic ash with the salts in the lake water altered the ash into various zeolite materials.
In 1756, the Swedish mineralogist Axel Fredrick Cronstedt discovered that stilbite, a natural mineral, visibly lost water when heated, and he named the class of materials zeolites from the classical Greek words meaning 'boiling stones.' Zeolites were considered an obscure group of minerals with unique properties for almost 200 years, and Cronstedt was remembered primarily for discovering the element nickel.
Considering all of these properties and abilities, zeolites commercial and environmental possibilities seem to be limitless. One example is the application of zeolites in landfills and at industrial sites, which can help prevent the release of a number of harmful or unwanted elements into the environment.
