く利用されている。BACKGROUND OF THE INVENTION Stabilized zirconium oxide thin films doped with zirconium oxide and stabilizers such as yttrium oxide, calcium oxide, magnesium oxide, etc. are used in various applications as alkali-resistant and wear-resistant films.

There are VD methods, plasma spraying methods, high frequency sputtering methods, etc., but due to the advantages such as high productivity, low temperature process, and low equipment cost, it is possible to mold a solution containing metal alkoxide by dipping or spin coating. Recently, a method of forming an oxide thin film by coating and heating has been frequently used.

して、溶液を安定化する方法が提案された。However, when producing a zirconium oxide thin film using this method, the zirconium alkoxide used as a raw material undergoes hydrolysis and condensation very quickly, so the stability of the solution against water and moisture is poor, and it is easily hydrolyzed. to form and precipitate zirconium oxide hydrate. Therefore, when applying a solution, it has been difficult to obtain a uniform and transparent coating layer. To this end, hydrolysis can be significantly suppressed by strictly controlling the humidity during application and by substituting some or all of the alkoxy groups of the alkoxide with groups capable of forming chelates, such as acetylacetone. A stabilizing method was proposed.

ある。[0004] However, the thin film formed using this solution contains a large amount of unreacted alkoxy groups and groups substituted for alkoxy groups because hydrolysis and polycondensation have not progressed sufficiently, and it is difficult to apply it to molded products. When an oxide thin film is obtained by heating, there is a problem in that a dense film cannot be formed due to pinholes and cracks that occur due to the decomposition of these groups.

。[Problems to be Solved by the Invention] The problem to be solved is that the zirconium oxide precursor solution prepared from zirconium alkoxide for thin film production has poor stability against moisture, and furthermore, it is difficult to apply the solution to molded objects. The problem is that a large amount of residual organic matter that causes pinholes and cracks is present in the precursor when forming an oxide thin film by firing, making it impossible to obtain a dense zirconium oxide thin film.

現できた。Since the zirconium oxide precursor polymer gel has almost no unreacted alkoxy groups, it is extremely stable against atmospheric moisture for a long period of time. If this precursor polymer can be made into a solution,
It is believed that a solution that is stable against moisture can be obtained, and that the thin film obtained by applying the solution will have almost no residual organic matter that causes pinholes or cracks. However, this precursor gel-like material is difficult to react to organic solvents.
Poor solubility. Therefore, as a result of research, the present inventor found that by placing a precursor gel in an organic solvent, adding a small amount of carboxylic acid, and heating, the precursor gel was completely dissolved and a transparent solution was formed. I discovered that. Addition of carboxylic acid converts the end groups of the precursor polymer into OCs with high solvent affinity.
It is thought that the substitution with the OR group made the precursor polymer soluble in alcoholic solvents. This invention has achieved the objective of preparing a solution for forming a thin film that is much more stable against moisture than conventional solutions prepared by suppressing the hydrolysis of zirconium alkoxide. Furthermore, by applying this solution to a molded product and heating it, we were able to achieve the objective of obtaining a dense zirconium oxide thin film with almost no residual organic matter, which had not been possible until now.

It has been difficult to prepare a solution for forming a thin film from this precursor gel due to its low solubility in organic solvents, but as described in the examples, the present invention enables the preparation of thin film by simply adding acetic acid. The gel-like material was easily dissolved in an organic solvent, making it possible to prepare a transparent precursor solution for thin film production. Furthermore, with this invention, it has become possible to dissolve the precursor gel, which contains almost no unreacted alkoxy groups, and use it as a solution for forming thin films, so this solution can be applied to molded objects by dipping or spin coating. , by firing,
It has become possible to obtain a dense zirconium oxide thin film with little residual organic matter, which was not possible with conventional alkoxide solutions. Furthermore, the transparent solution in which the precursor gel of the present invention is dissolved does not contain alkoxide molecules having unreacted hydrolyzable alkoxy groups. Another advantage is that it can be stored stably for a long time without being affected by moisture. The thin film manufacturing method of the present invention yields a transparent and dense zirconium oxide thin film, and thus greatly expands the use of zirconium oxide thin films as optical materials.
