Abstract
An environment-purifying material is obtained by immersing a carrier with a titanium oxide film coated on its surface or a substrate comprising titanium oxide particles, in a pseudo-body fluid containing an excessive amount of calcium phosphate, and then coating the surface of the substrate with a porous calcium phosphate film that easily adsorbs toxic substances and that is inactive as a photocatalyst.
Claims22
An environment-purifying material wherein a porous apatite film is coated on the surface of a particulate substrate, the surface comprising titanium oxide.
An environment-purifying material, comprising a substrate coated with a porous apatite film, wherein said substrate comprises a carrier having a surface coated with an anatase titanium oxide film.
An environment-purifying material manufacturing method wherein a porous calcium phosphate film is coated on the surface of a substrate having a surface comprising titanium oxide by immersing said particulate substrate in a pseudo-body fluid containing calcium phosphate.
