What is zeolite? Did you know? Here I will tell you about the scientific facts about what it is zeolite. You'll know the meaning of the zeolite and you will know also what is the use of zeolite and also I mentioned disadvantages. Please read below.

Zeolites are aluminosilicate minerals commonly used as an absorbent micropore commercial. The term zeolite was originally granted in 1754 by Swedish mineralogist, Axel Fredrik Cronstedt, who observed that when the material stilbite is heated, it produces large amounts of water vapor that has been absorbed by the material. Based on this, he called the material zeolite, from the Greek meaning Zeo boil and Lithos, which means stone.

Already there are 194 zeolite framework has been found, and about 40 between the zeolite framework is found in nature.

Zeolites are used as a water purifier

 

Zeolites are used as a water purifier in the world industry, catalysts and nuclear reprocessing. Utilization primarily as a laundry detergent product. They are also used in medicine and agriculture.

Natural zeolites

Zeolites have a porous structure that can accommodate a large number of cations, Na +, K +, Ca2 +, Mg2 + and others. Positive ions are tenuous and can be easily replaced in the contact solution. Some of the common mineral zeolites are analcime, chabazite, clinoptilolite, heulandite, natrolite, phillipsite, and stilbite. Examples of zeolite mineral chemical formula is: Na2Al2Si3O10.2H2O, the formula for natrolite.

Natural zeolites are formed when volcanic rock and ash layers react with ground water containing alkaline. Zeolites also crystallized in post-sediment environments in long periods of thousands to millions of years in shallow marine basins. Zeolites are found in nature is rarely pure and are contaminated with various types of minerals, metals, quartz and other types of zeolites. For this reason, zeolites are obtained naturally expelled from many commercial applications where uniformity and purity are needed.

Production of natural zeolite

Today, the world's annual production of natural zeolite is about 4 million tons. 2.6 million tons of which are marketed to China for use in the concrete industry. Eastern Europe, Western Europe, Australia and Asia are the main leaders of the world's supply of natural zeolites. Only 57.400 metric tons of zeolite (only 1% of world production) are able to produce North America, and only just recently realized the potential of the North American market from the zeolite.

Benefit zeolites

Synthetic zeolites are used as catalysts of petrochemical industry, for instance in fluid catalytic solution and water solution. Zeolite molecules break down in small sizes, which causes changes in the structure and reactivity. Hydrogen forms of zeolites (supplied by ion exchange) is a strong solid acid and can be catalytic acid reaction container, such as isomerization, alkylation and solutions. Modality specific activation most zeolite catalysts used in petrochemical applications involves the reaction of Lewis acid sites of Quantum-chemical.

Molecular structure of micropore zeolite ZSM-5 type

Zeolites can also be used as solar thermal collectors and for adsorption refrigerator. In this application, the high heat of adsorption and ability to hydrate and dehidration exploited while maintaining the stability of the structure. Hygroscopic properties coupled with the exothermic reaction (heat producing) inherent when transitioning from a dehydrated form of hydration makes natural zeolites useful in taking waste heat and solar thermal energy.

Thomsonit zeolite is a mineral that is used for jewelry. Thomsonit nodules have concentric rings with a combination of black, white, orange, pink, red and green shaded lot. Some nodules have copper contamination and the rarest is thomsonit who have "eyes" of copper. When polished lapidary, thomsonit sometimes show chatoyansi.

Zeolites can be used as a molecular sieve in a vacuum pumping cryosorpsi style.

Both synthetic and natural zeolites have been used in animal nutrition, especially to improve performance and based on the physicochemical properties essentially, they are also tested and found to be useful in preventing the toxicity of ammonia and heavy metals as well as the intake of radioactive elements decay and metabolic framework.

Zeolites are an effective ammonia filter, but should be used with caution, especially with tropical coral reefs are sensitive to water chemistry and temperature.

So you have them know about what is zeolite, thanks for reading!
