Agualite.
Agualite is a brand of zeolite in the form of granules.
The Agualite is the name given to her by Aguagreen granulate consisting of zeolites and polycrystals.
This mixture is used in the catalytic filtration his water refiners Aguapure.
Where does the zeolite, rock crystal ?
Zeolite is an inorganic microporous natural mineral silicates belonging to the group. There are over forty zeolite families.
Overview of some types of zeolite crystals:
The time discovery zeolites
1756.
The Swedish mineralogist Axel Fredrik Cronstedt discovered the first zeolite mineral, called Stilbite. It recognizes zeolites as a new class of minerals composed of alumino-silicate hydrates and alkaline earths. Because of its nature intumescent when this mineral is heated by a torch flame, Cronstedt called this mineral “zeolite”.
1840.
Alexis Damour observed that the zeolite crystals can be reversibly dehydrated without any apparent change in their morphology and transparency.
1845.
Schafhautle reports the hydrothermal synthesis of quartz by heating a silica gel with water in an autoclave.
1850.
Thompson Way and clarify the nature of the ion exchange in land.
1858.
Eichhorn demonstrates the reversibility of ion exchange in zeolites.
1862.
S. C.Deville reported the first hydrothermal synthesis of zeolite, levynite.
1896.
After observing that various liquids such as alcohol, benzene and chloroform were occluded in the zeolite, Friedel develops the idea that the structure of the dehydrated zeolites consists of a spongy matrix ouverte.En 1909 Grandjean observed that the dehydrated chabazite adsorbs ammonia, air, hydrogen and other molecules.
1925.
Weigel and Steinhoff identified the first “molecular sieve” effect. They noted that dehydrated “chabazite” crystals quickly adsorb the following products:
- water,
- methyl alcohol,
- ethyl alcohol,
- formic acid.
And that the following products were not adsorbed during the tests:
- acetone,
- ether,
- benzene.
1927.
Leonard describes the first use of X-rays for identification in the inorganic synthesis.
1930.
The first structures of zeolites are determined by Taylor and Pauling.
1932.
Mc Bain establishes for the first time the term “molecular sieve” to define porous solids that act as sieves on a molecular scale. In the mid 1930s, the literature describes ion exchange, adsorption, molecular sieves, structural and mineral properties of zeolites and reports the synthesis of many zeolites. Barrer began his pioneering work in the adsorption of zeolites and their synthesis. It offers the first classification, based on molecular size considerations. In 1948, he reported the first complete synthesis of a zeolite similar to the natural zeolite under the name mordenite (Wikipedia).

Aguagreen creates the Agualite brand.
Space science and environmental interest in the zeolite.
Zeolite crystals which have been produced on earth are smaller and less regular than those which have been designed in space. This experience driving with the “Center for Advanced Microgravity Materials Processing at Northeastern University in Boston” was to better understand the synthesis of zeolites to improve in particular the treatment of … oil and reduce fuel costs !

Some economic data.
Global annual production of natural zeolite:
- about 4 million tonnes,
- 2.6 million tonnes for Chinese cements.
Regions and countries mainly producing and supplying zeolite in the world:
- Eastern Europe,
- Western Europe,
- Australia.
North America produces 57,400 tonnes of natural zeolite, about 1.5% of world production (source: U.S. Geological Survey, 2004).
