    • A ceramic slurry composition has a powdered ceramic uniformly dispersed therein without excessive damage thereto. A method for producing a ceramic green sheet using the ceramic slurry composition and a method for producing multilayer ceramic electronic devices are also disclosed. The ceramic slurry composition contains the powdered ceramic, a dispersing agent, a binder and a solvent, in which an anionic dispersing agent is used as the dispersing agent, and the content of the anionic dispersing agent is set to be such that the total acid content thereof corresponds to about 10 to 150% of the total base content of the powdered ceramic. In addition, the powdered ceramic having an average particle diameter of about 0.01 to 1 &mgr;m is used.

    • The invention relates to a multilayered metal oxide film formed on a glass substrate by the sol-gel process. The film has a first metal oxide layer formed on the glass substrate and a second metal oxide layer formed on the first layer. To make the first layer minutely rough, at least two sols are respectively prepared from at least one compound selected from the group consisting of metal alkoxides and metal acetylacetonatos, such that polymers of the sols have different average molecular weights. Then, the at least two sols are mixed with a solvent so as to prepare a first coating solution. The first coating solution is applied to the glass substrate so as to form thereon a first sol film. The thus coated glass substrate is heated so as to transform the first sol film into the first metal oxide layer. To form a water-repellent metal oxide film on the first layer, a silane compound containing a fluorocarbon group is mixed with a solvent so as to prepare a second coating solution. After that, the second coating solution is applied to the first metal oxide layer so as to form thereon a second sol film. Then, the glass substrate is heated so as to transform the second sol film into the second metal oxide layer which is water-repellent.
    • 本发明涉及通过溶胶 - 凝胶法在玻璃基板上形成的多层金属氧化物膜。 该膜具有形成在玻璃基板上的第一金属氧化物层和形成在第一层上的第二金属氧化物层。 为了使第一层微小,至少两种溶胶分别由至少一种选自金属醇盐和金属乙酰丙酮酸的化合物制备,使得溶胶的聚合物具有不同的平均分子量。 然后,将至少两种溶胶与溶剂混合,以制备第一涂布溶液。 将第一涂布溶液施加到玻璃基板上,以在其上形成第一溶胶膜。 将如此涂覆的玻璃基板加热,以将第一溶胶膜转化为第一金属氧化物层。 为了在第一层上形成拒水性金属氧化物膜,将含有碳氟化合物基团的硅烷化合物与溶剂混合以制备第二涂布溶液。 之后,将第二涂布溶液施加到第一金属氧化物层上,以在其上形成第二溶胶膜。 然后,对玻璃基板进行加热,将第二溶胶膜转化为防水性的第二金属氧化物层。
