呈するのである。Means for Solving the Problems A magnetic ceramics for achieving the above object is composed of a porous ceramics containing a magnet, or an antibacterial agent such as metallic silver or copper and a porous ceramics containing a magnet. It is a feature.
About 90% of the plant body is water, and various reactions related to growth in the plant body are performed as ionic reactions. Therefore, it is conceivable that the presence of magnetism and magnetic field in such a reaction process may affect those reactions. In particular, since plant growth proceeds through cell membranes and the like, it is considered that the root growth is promoted by the magnet in the porous ceramics embedded in the soil. Further, when placed in a water tank of a farm, the magnetic force activates the water to make the water last longer, and by mounting it in a purifying device for drinking water or the like, the water can be made mellow. Next, since porous ceramics can retain air in a large number of fine pores, when embedded in soil, the air in the pores, particularly oxygen, activates the soil. Further, by incorporating an antibacterial agent such as metallic silver or metallic copper into the porous ceramics, it exhibits an antibacterial action against water or soil.

-5 mm Sr ferrite crystal was prepared. This was immersed in a separately prepared ceramic slurry to coat the periphery of the clinker to prepare a magnetic ceramic of about φ10 mm, which was dried and then baked at about 600 ° C. to be magnetized. The ceramic slurry was prepared by mixing ceramic powder, a solvent, and an organic binder, adding silver oxide and silver carbonate, and kneading. General sewage (200 ml) was prepared, 10 g of the previously washed magnetic ceramics was put therein, and after stirring for 5 seconds, the number of coliform bacteria in / ml was measured after 1, 3 and 24 hours in a stationary state. For comparison, a ceramic having a diameter of about 10 mm and containing neither clinker nor silver was prepared and tested. The results are shown in Table 1.
