Nature: a class of widely distributed silicate minerals. Linked together by sharing oxygen from the silicon-oxygen tetrahedron and aluminum-oxygen tetrahedron composed of three planes Ludwig, trivalent aluminum tetravalent silicon replaces the excess negative charge generated by a price or the divalent metal cations, typically alkali metal or alkaline earth balanced by metal cations.

Is now found in nearly 40 species, mainly well-zeolite, laumontite, Ca Cross zeolite, sodium zeolite, mordenite, film zeolite, clinoptilolite, zeolite Ling, octahedral zeolite . Zeolite adsorption and ion conversion, and because each has its particular uniform zeolite pore size (0.3 ~ 1nm), only through the appropriate size of the molecules. Widely used as a catalyst or carrier, drying, feed additives, soil amendments, water purification agents, plastic and paper packing, extracting potassium from sea water and so on. And a large number used in cement production.

Nature has found 30 kinds of zeolite, the more common [1] analcime, Ling zeolite, calcium zeolite, zeolite films, sodium zeolite, mordenite, zeolite-hui, have to contain calcium, sodium-based. The number of their water content with external temperature and humidity changes. Crystal system with the mineral crystal belongs to vary species to monoclinic and orthorhombic (orthorhombic) in the majority. Analcime, Link often has equiaxed crystalline zeolite, zeolite films, was Stilbite plate, wool zeolite, acicular or fibrous mordenite, zeolite and calcium cross-hui boiling Dan Shuangjing common. Pure zeolite are colorless or white variety, but can be due to impurities was mixed with a variety of light-colored. Glass luster. Cleavage varies with the crystal structure. Mohs medium. The proportion of between 2.0 to 2.3, containing barium is up to 2.5 ~ 2.8.
