<P>PROBLEM TO BE SOLVED: To provide a method for producing an environmental material, and also to provide a product for cleaning environment. <P>SOLUTION: The method for producing the environmental material comprises immersing a base material having a surface composed of titanium oxide into a water solution containing calcium ions, phosphate ions and/or hydrogenphosphate ions and applying microwave irradiation of the base material, thus enabling the surface of the base material to carry a porous calcium phosphate. The method for producing the environmental material comprises immersing the base material into the water solution containing the calcium ions, the phosphate ions and/or the hydrogenphosphate ions and applying microwave irradiation of the base material, and thereafter drying it at 40-600°C. The product for cleaning environment is characterized by containing the environmental material in which the porous calcium phosphate is carried on the surface of the base material through immersing the base material having the surface composed of the titanium oxide into the water solution containing the calcium ions, the phosphate ions and/or hydrogenphosphate ions and through applying microwave irradiation of the base material. <P>COPYRIGHT: (C)2003,JPO |
