Zeolite is an ore, which first discovered in 1756. Swedish mineralogist Axel Fredrik Cronstedt discovered that there is a type of natural aluminosilicate ore that boils when burned, so it named it "zeolite" (Swedish zeolit). "Stone" (lithos) meaning "boiling" (zeo) in Greek. Since then, people's research on zeolite has continued to deepen.
The general chemical formula of zeolite is: AmBpO2p·nH2O, and the structural formula is A(x/q)[ (AlO2)x(SiO2)y] ·n(H2O) where: A is Ca, Na, K, Ba, Sr and other cations, B Is Al and Si, p is the valence of cations, m is the number of cations, n is the number of water molecules, x is the number of Al atoms, y is the number of Si atoms, (y/x) is usually between 1 and 5, (x+y ) Is the number of tetrahedrons in the unit cell.
Molecular weight: 218.247238
Zeolite has ion exchange properties, adsorption and separation properties, catalytic properties, stability, chemical reactivity, reversible dehydration properties, electrical conductivity and the like. Zeolite is mainly produced in the fissures or amygdala of volcanic rocks, co-existing with calcite, chalcedony, and quartz; it is also produced in pyroclastic sedimentary rocks and hot spring deposits.
Zeolite ore is widely used in
1.Adsorbent and desiccant
4.Other usage (sewage treatment, soil amendments, feed additives)
Natural Zeolite ore is an emerging material, which is widely used in industry, agriculture, national defense and other sectors, and its uses are still being explored. Zeolite is used as ion exchanger, adsorption separation agent, desiccant, catalyst, cement mixing material.  In the petroleum and chemical industries, it is used as a catalytic cracking, hydrocracking, and chemical isomerization, reforming, alkylation, and disproportionation of petroleum; gas and liquid purification, separation and storage agents; hard water softening , Seawater desalination agent; special desiccant (dry air, nitrogen, hydrocarbons, etc.). In the light industry, it is used in papermaking, synthetic rubber, plastics, resins, paint fillers and quality colors. In national defense, space technology, ultra-vacuum technology, development of energy, electronic industry, etc., it is used as an adsorption separator and desiccant. In the building materials industry, it is used as a cement hydraulic active admixture to burn artificial lightweight aggregates to make lightweight and high-strength plates and bricks. Used as a soil conditioner in agriculture, it can protect fertilizer, water, and prevent pests and diseases. In the livestock industry, it can be used as feed (pigs, chickens) additives and deodorants, etc., which can promote the growth of livestock and increase the survival rate of chickens. In terms of environmental protection, it is used to treat waste gas and wastewater, remove or recover metal ions from wastewater and waste liquid, and remove radioactive pollutants in wastewater.
In medicine, zeolite is used to determine the amount of nitrogen in blood and urine. Zeolite has also been developed as a health product for anti-aging and removing heavy metals accumulated in the body.
In production, zeolite is often used in the refining of granulated sugar.
