Characteristics of zeolite

Zeolite is zeolite family of minerals in general, is an aqueous alkali metal or alkaline earth metal aluminum silicate mineral. By zeolite mineral characteristics into frame, sheets, fibers and Unclassified of four, according to pore system characteristics into one-, two-, three-dimensional system. Any zeolite by silicon-oxygen tetrahedron and aluminum oxygen tetrahedra. Tetrahedron can only apexes, i.e. sharing one oxygen atom, and not "side" or "face" is connected. Aluminum-oxygen tetrahedron itself can not be connected, there have been at least one silicon-oxygen tetrahedron. The silicon-oxygen tetrahedron can be directly connected. Silicon-oxygen tetrahedron silicon, aluminum atoms can be replaced by aluminum-oxygen tetrahedron constituted. However, aluminum atoms are trivalent, so aluminum tetrahedron, there is an oxygen atom price has not been neutralized, a charge imbalance is generated, so that the whole is negatively charged tetrahedral aluminum oxide. In order to maintain a neutral, positively charged ions must be offset to compensate for the generally alkali metal and alkaline earth metal ions, such as Na, Ca and Sr, Ba, K, Mg and other metal ions. Because zeolite has a unique internal structure and chemical properties of crystallization, thus making the 5a zeolite powderhas a variety of industrial and agricultural use of the available features.
The world has discovered natural zeolite is generally light gray, sometimes red meat. In our hands, obviously felt lighter than stone, which is fine because the interior is filled with zeolite cavities and channels, much more complex than the hive. If the zeolite compared to hotels, so within a cubic micron of this "super hotel" as much as one million "room"! These rooms can be based on "Passenger" (molecules and ions) sex, height, fat, thin, different automatic door or onto trains, hobby, will not let the "Fat Man" to "thin" the room to go, does not make tall Shorty and sharing a room. According to the characteristics of zeolite molecular screening of people use it to get good results. This has particular significance for the recovery of copper, lead, cadmium, nickel, molybdenum and other metal particles in industrial waste.
Zeolite having adsorption, ion-exchange, acid catalysis and heat resistance properties, it is widely used as adsorbents, ion exchangers and catalysts, may also be used for drying gases, purification and sewage treatment and so on. Zeolite also has a "nutritional" value. 5% of the synthetic zeolite powders in the feed, make livestock grow faster, Tizhuang fresh meat, egg production rate.
Due to the nature of the porous silicate zeolite, the wells there is a certain amount of air, is often used riot boiling. When heated, the air inside the hole escape, acts as a gasification nuclei, small bubbles are easily formed on the corners.
