Definitions
- This invention relates to a method of preparing a zirconia film, and more particularly to a method of preparing a zirconia film by using a zirconium acetylacetonate suspension formed into a sol (or colloidal solution).
- Known as methods for preparing zirconia films at low temperatures are (1) a method in which a substrate is coated with a zirconium alkoxide solution comprising zirconium propoxide or zirconium butoxide, followed by hydrolysis and dehydration condensation (Japanese Patent Publication No. 48865/1984, (2) a method in which a substrate is coated with a zirconium octylate solution followed by thermal decomposition (Japanese Unexamined Patent Publication No.
- the concentration of the zirconium alkoxide may be lowered to retard the rate of hydrolysis in the air, but a lowered concentration makes it necessary to carry out the coating several times to obtain a thick film, thus increasing the coating times.
- the hydrolysis rate of the zirconium octylate is lower than that of the zirconium alkoxide, and hence no gel is formed even when coated with its alcohol solution having a higher concentration (not less than about 25 g/l). No problems may therefore arise if the alcohol solution prepared is completely used every time the coating is carried out, but, when the solution is not completely used, the remaining solution must be used in a short time before it can be reused.
- the zirconium octylate has also a large molecular weight of the organic acid group with respect to zirconium, and therefore the yield of zirconia is as low as about 19%.
- the solution can attain a superior workability and give a thicker film at the first coating than other methods.
- the acetylacetonate metallic complex is solid, its solubility to organic solvents such as alcohols and aromatic hydrocarbons is not so good that a suspension thereof can only have a concentration of about 0.05 mol/l. For this reason, the film thickness obtained by the first coating is still insufficient, and it has been necessary for obtaining a thick film to use as a solvent a highly viscous solvent such as methyl cellulose or glycol, or increase the coating times.
- An object of the present invention is to provide a method of preparing a zirconia film with a sufficient thickness by the first coating.
- Another object of the present invention is to provide a method of preparing a zirconia film by using a coating solution having a superior shelf stability and achievable of a good workability.
- the method comprises coating a substrate with a zirconium acetylacetonate suspension formed into a sol obtained by carrying out hydrolysis of zirconium acetylacetonate by adding water in an amount of from 10 to 12 mols per mol of zirconium acetylacetonate in an organic solvent solution comprising zirconium acetylacetonate, or an organic solvent solution comprising zirconium acetylacetonate and a different type of acetylacetonate metallic complex added.
- This method can obtain a thick film at the first coating, and the coating solution used in the method can be stably stored for a long period of time.
- the zirconium acetylacetonate (CH3COCHCH3)4Zr is a coordinate bond compound, and hence can be formed into a sol by carrying out hydrolysis by adding water, thus making its concentration higher than that in a saturated organic solvent solution. This higher concentration makes it possible to apply the compound in a large quantity than that of a saturated organic solvent solution at the first coating, to provide a thick zirconia film after heating.
- the theoretical water quantity necessary for completely hydrolyzing the zirconium acetylacetonate is 4 mols per mol of zirconium acetylacetonate, but the water is added in an amount of from 10 to 12 mols.
- An amount less than 10 mols can not bring about complete dissolution of the zirconium acetylacetonate, resulting in a formation of a suspension, making it impossible to give a thick film at the first coating.
- An amount more than 12 mols may result in a white and turbid solution in several minutes after hydrolysis to produce precipitates, making it impossible to carry out coating.
- acetylacetonate metallic complex in addition to the zirconium acetylacetonate for the purpose of improving the properties of the zirconia film, it is also hydrolyzed by water and formed into a sol, and thus a thick film can also be obtained.
- It includes, for example, titanium acetylacetonate, aluminum acetylacetonate, potassium acetylacetonate, and diethylthallium acetylacetonate, which can be readily hydrolyzed.
- Thermal decomposition after the coating of the zirconium acetylacetonate (and/or the different type of acetylacetonate metallic complex) formed into the sol may be carried out at 200°C or more in the same manner as conventionaly done.
- the film may be heated at from 500 to 1,200°C.
- the resulting zirconia films had a film thickness of 0.25 ⁇ m in the instance where the suspension formed into a sol was used, and 0.05 ⁇ m in the instance where the control suspension was used. These films achieved a strong adhesion, and were free from generation of cracks and uneveness of film thickness.
- the zirconium acetylacetonate suspension formed into a sol was also allowed to stand for a week in the air (relative humidity: 60 % at 25°C) and thereafter again used, but the same results were obtained as those before it was allowed to stand,
- zirconia films were formed on SUS304 stainless steel sheets of 0.4 mm thick each in the same procedures as Example 1, to obtain the results that the zirconia films had a film thickness of 0.13 ⁇ m in the instance where the suspension formed into a sol was used, and 0.025 ⁇ m in the instance where the control suspension was used.
- the stainless steel sheets on which these zirconia films were formed were heated at 800°C for 10 hours, and gains in weight by oxidation was measure to find that they were 0.06 mg/cm2 in the instance where the film was formed using the suspension formed into a sol, and 0.11 mg/cm2 in the instance where the film was formed using the control suspension.
- SUS304 stainless steel sheets were respectively coated with the resulting suspension formed into a sol and the suspension (control) having been not formed into a sol, following the same procedures as Example 1, followed by heating to thus form an oxide film comprising ZrO2, TiO2 and AIO3 uniformly dispersed.
- the film formed using the suspension formed into a sol had a thickness of 0.22 ⁇ m.
- the film formed using the control suspension had a thickness of 0.04 ⁇ m.
