Abstract: PURPOSE:To form the subject superconductive thin film having a high critical temperature at a low cost by forming a thin film of a solution composed of respective alkoxides or alkoxyalkolates of Bi, Ca, Sr, Cu and Pb, an alkanolamine and an alcohol on a substrate, gelling and then sintering. CONSTITUTION:A mixed solution containing respective alkoxides (methoxide, ethoxide, propoxide, butoxide, etc.) or alkoxyalkolates (methoxyethylate, ethoxyethylate, propoxyethylate, butoxyethylate, etc.) of respective metals such as Bi, Ca, Sr, Cu and Pb, an alkanolamine and an alcohol is coated on a heat- resistant substrate to form a thin film. The resultant thin film is gelled by drying and then sintered at 750 to 870 deg.C, thus forming the objective superconductive thin film represented by (Bi1-pPbp)(Sr1-qCaq)xCuyOz (0 =105K and Jc>=10 A/ cm .

Abstract: PROBLEM TO BE SOLVED: To reproducibly synthesize a MFI-type thin zeolite film with a size of a μm order. SOLUTION: A reaction solution with the following composition. SiO 2 : an organic amine : tetrapropyl ammonium bromide : H 2 O=1:x:y:z (wherein the compositional ratio is molar ratio; x=0.25-5; y=0.4-8; and z=100-300) is heated in a closed vessel at a temperature of ≥100°C and maintained for ≥1 hour. The MFI-type zeolite obtained by this method is applied on a substrate to be oriented, which is useful as the substrate in manufacturing a zeolite film. COPYRIGHT: (C)2003,JPO

Abstract: PURPOSE:To obtain a Pb-doped Bi-type superconducting thin film having high critical temperature at a low cost from a metal alkoxide or alkoxy alcoholate by using a specific metal excluding rare-earth elements as the above metal. CONSTITUTION:A mixed solution containing methoxides, ethoxides, propoxides, butoxides, methoxyethylates, ethoxyethylates, propoxyethylates or butoxyethylates of Bi, Ca, Sr, Cu and Pb; mono-, di- or triethanolamine, mono-, di- or tri-1(or 2)-propanolamine; and methanol, ethanol, propanol, butanol or methoxy-, ethoxy-, propoxy- or butoxyethanol are prepared beforehand. A thin film of the mixed solution is formed on a substrate, gelatinized and calcined to form a superconducting thin film on the substrate.

Abstract: PURPOSE:To form a PZT thin film having excellent uniformity with a simple operation by coating a substrate with an alcohol solution composed of alkoxides of Pb, Zr and Ti added with ethanolamine, drying and gelatinizing the coating film and calcining the product. CONSTITUTION:A thin film of lead titanate zirconate (PZT) can be produced by mixing (A) a lead alkoxide or a lead salt [selected from methoxide, ethoxide, propoxide, butoxide and acetate (hydrate)], (B) a Zr alkoxide (selected from methoxide, ethoxide, propoxide and butoxide), (C) a Ti alkoxide (selected from methoxide, ethoxide, propoxide and butoxide), (D) (mono, di or tri)ethanolamine and (E) a 1-4C alcohol, forming a thin film of the mixture on a substrate by dip-coating process, drying and gelatinizing the coating film, introducing the gelatinized thin film together with the substrate into a furnace and calcining at 600-800 deg.C.

Abstract: PURPOSE:To obtain the titled homogeneous thin film useful as protective films, dielectric films, etc., without causing cracking or uneven thickness, by forming a thin film of a blend of a specific zirconium alkoxide with a specific hydrolytic inhibitor and solvent on a substrate, drying, gelatinizing and calcining the resul tant thin film. CONSTITUTION:A thin film of a blend containing at least one zirconium alkoxide selected from zirconium methoxide, ethoxide, propoxide and butoxide, one hydrolytic inhibitor selected from monoethanolamine, diethanolamine and triethanolamine and one solvent selected from methanol, ethanol, propanol and butanol is formed on a substrate (e.g. quartz glass plate), then dried and gelatinized at about ordinary temperature-80 deg.C. The resultant thin film with the substrate and all are subsequently placed in a furnace, heated to 500-1500 deg.C at 1-10 deg.C/min rate and kept for a given time, calcined and cooled to ambient temperature at 1-10 deg.C/min rate to afford the titled thin film.
