Due to contain electricity price low ionic radius larger metal ions and combining state of the water, the water Activated zeolite powders in the heated continuously losing, but crystal skeleton structure remains the same, has formed many of the same size of the cavity, the cavity has many of the same diameter pores is linked together, these small cavity diameter size uniform, can channel diameter smaller than the 4a zeolite powder to the interior of the cavity, and channel than large molecules are excluded, so the molecules of different diameter size shape, the degree of different polarity molecules, the boiling point of different molecules, degree of saturation of different molecular separation, which have the function of the "screening" molecules, known as molecular sieve. The molecular sieve in metallurgy, chemical industry, electronics, petrochemical, natural gas and other widely used in industry.
