In this study, the systematic application technologies that include fundamental technology and processing technology were investigated for natural zeolite. Development engineering that is bioreactor, antibacterial deodorant, ameliorant, electrode, Far Infrared Rays (FIR) radiation body, remover for wastewater treatment and Electro-Magnetorheological Fluids were constructed for practical uses.In consequence, it is clear that a natural zeolite was transferred to zeolite P1 by the alkali treatments. Hygroscopic property was improved as an absorbent material. A natural zeollte, easily vitrifed and blown at 1300 degree with a high porosity and diameter of 5-100 um, was used to immobilize Saccharomyces cerevisiae at 3. 6 *10^8 cells/ml carrier. When the abilities of natural zeolite carrier were compared with glass beads, the capacity for immobilization and alcohol fermentation activity were, respectively, 2'-fold higher and 1. 2-hold higher than that of glass beads. In the meantime, we made the electrode that had electric conductivity and ion absorption from the sinter of a carbon powder and a natural zeolite. We constructed the method to make the FIR radiaton body using a naturai zeolite and the characteristics of radiation body were evaluated. In addition, this radiator was used as FIR radiation light source, and thermography inspection of the breast cancer was tried. From the thermal camera image, the result showed that the temperature of the cancer that reached the skin difters from the temperature of the normal tissue. Simultaneously, it was proven that it might be able to guess the progress of the cancer from the difference of cancer and temperature change pattern of the normal tissue. We examined the adsorptivity of a zeolite in terms of crystallographically and evaluated a soil conditioner property of a natural zeolite by a cultivation test.
