(Ortho titanic acid) is reacted with hydrogen peroxide to obtain a titanium peroxide solution.
- the titanium peroxide solution does not substantially contain a component (for example, a carbon component or the like) which inhibits obtaining an anatase type titanium oxide film at a low processing temperature. It is particularly preferred that the titanium peroxide solution consists essentially of titanium, oxygen, and hydrogen.
- the solution generally called a titanium peroxide solution is usually a sol solution of an amorphous titanium oxide obtained by causing hydrogen peroxide to act on a gel-like titanium hydroxide gel (ortho-titanic acid).
- the titanium in the film oxygen, because they contain only hydrogen, there is no substance that inhibits the crystallization, the anatase T i 0 2 film at a low temperature It is likely to be obtained.
