Aluminosilicate compound

Aluminosilicate compound having a cubic lattice, the alumina is mainly composed of the open connection through an oxygen bridge skeleton structure, there are a lot of uniform pore size and pore structure grace molecular sieves  are arranged neatly, the inner surface area of ​​a large hole. Also contains a lower price and ionic radius larger metal ions and compounds of state water. As water molecules in the continuous loss of heat, molecular sieve manufacturers  but the same crystal framework structure, the formation of many of the same size of the cavity, the cavity of the same diameter,molecular sieve drying, there are many pores are connected, the diameter of these small pores of uniform size, pore ratio can adsorption of molecules having a small diameter into the interior cavities in the regeneration of molecular sieves  past, but have the molecules larger than the pore exclusion, different shapes can thus molecular diameters, different degrees of polarity of the molecule, molecules having different boiling points and different degree of saturation of molecular separation open, that has the effect of "screening" of molecules, so called molecular sieves. Currently zeolite widely used in metallurgy, chemical industry, electronics, petrochemical and natural gas industries.
