Abstract: A process for forming a dense, epitaxial metal oxide film on a single crystal substrate, includes cleaning the surface of the single crystal substrate, contacting the cleaned surface with a polar organic compound such as methanol, so that the cleaned surface adsorbs the polar organic compound, then applying a hydrocarbon solvent solution containing at least one organic group-containing metal compound on the polar organic compound-adsorbed surface, and then heating the substrate to decompose the organic group-containing metal compound and to form a dense epitaxial metal oxide film on the substrate. The cleaning is preferably by ultrasonic cleaning. The substrate is preferably alumina. The hydrocarbon solvent is preferably hexane, octane, benzene, toluene or tetralin. The organic group-containing metal compound may be a metal salt of an organic acid, a metal phenslate, or a metal organic chelate. A preferred film is of iron oxide but oxides of Fe,Co,Ni,Ti,Cr or Mn may also be deposited.

Abstract: There is disclosed a method for producing a metal oxide, which comprises the steps of: dissolving a metal organic compound (e.g. a metal organic acid salt, a metal acetylacetonato complex, and a metal alkoxide having an organic group with 6 or more carbon atoms) in a solvent to provides a state of solution, applying the solution onto a substrate, drying the solution, and subjecting the resultant substrate to irradiation with a laser light of a 400 nm or less wavelength, to form a metal oxide on the substrate. According to that method, a metal oxide can be produced without applying a heat treatment at a high temperature of the degree adopted in the conventionally known application thermal decomposition method.

Abstract: A superconductive material including a substrate and a superconductive layer of a double oxide of metals provided on the substrate is produced by a method which comprises the steps of: (a) providing a solution containing a blend of metal compounds having a composition corresponding to that of the double oxide; (b) applying the solution on the substrate to form a liquid film; (c) drying the liquid film; and (d) calcining the dried film to convert the metal compounds into the superconductive double oxide of the metals. s

Abstract: PURPOSE:To produce the superconductor having good stability by preventing the reaction of a superconductive complex metal oxide and a base body at the time of producing this oxide. CONSTITUTION:This process for production of the superconductor consists (A) calcining an inorg. film which is formed on the base material and consists of (1) barium carbonate, (2) rare earth metal oxide, (3) copper oxide, and (4) noble metal and/or the oxide thereof, at the temp. at which the reaction between this film and the base material does not substantially arise in an inert gaseous atmosphere of

Abstract: PURPOSE:To make it possible to efficiently perform the charging and discharging processes by using a water solution containing hydrogen chloride, ferrochloride and ferrichloride while regulating its hydrogen chloride concentration within a specific range. CONSTITUTION:A charging process in which ferrochloride in a water solution containing hydrogen chloride, ferrochloride and ferrichloride is partly oxidized into ferrichloride at an anode electrode to generate hydrogen at a cathode electrode and a discharging process in which generated hydrogen is oxidized at the anode electrode while reducing a water solution containing generated ferrichloride at the cathode electrode to generate ferrochloride and hydrogen chloride constitute the captioned method. Thereby, the respective water solutions containing chlorinated iron have hydrogen chloride concentration, desirably 2-7mol/kg-H2O and the total iron concentration of the primary iron and the secondary iron, desirably 1-4mol/kg-H2O, while a mol ratio of the primary iron to the secondary iron is desirably in the range of 1/3-3/1.
