Abstract
A hydrophilic treatment by the use of a surface active agent and the like is not required for a base even the surface of which is water-repellent or thermoplastic when a viscous amorphous type titanium peroxide is used for fixing a base as a binder. In addition, a thin layer of a photocatalyst semiconductor, a dielectrical ceramics or an electrical ceraincs can be easily formed by adhering particles of a photocatalyst semiconductor, a dielectrical ceramics or an electrical ceramics to the layer of a viscous amorphous type titanium peroxide, which is a layer as a binder, in a homogeneously floating state gas. Furthermore, a layer of a titanium oxide having a photocatalyst function can be formed when a base is fixed with a viscous amorphous type titanium peroxide.
Claims2
A method for fixing a titanium oxide layer on a substrate, which comprises the steps of:
- coating the substrate with an amorphous type titanium peroxide sol, thereby providing a titanium peroxide sol coating;
- attaching fine particles of titanium oxide over the titanium peroxide sol coating;
- and then drying and calcining the coated substrate at 250° C. or more.
