摘要： 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

摘要： PURPOSE:To form the selective absorption film surface prominent in selective absorption property, heat resistant property and durability by forming the film of nickel plating on a metallic base plate and forming thereon the film of Co3O4 of specified thickness. CONSTITUTION:The nickel plating film is formed on the surface of the metallic base plate, such as aluminum plate, stainless steel plate or the like, by employing watt bath or sulfamine acid bath. Next the complex of organic carboxylate or beta diketones of cobalt is dissolved in organic solvent and the solution is coated on the film of nickel plate by brush coating, dipping, spraying or the like so that the thickness of the film of Co3O4 becomes 0.5mum or less after heat treatment. Then the film is treated by heat under the temperature of 300- 800 deg.C and thereby forming the film of Co3O4. According to this method, the solar heat selective absorption surface, prominent in the selective absorption property, heat resistant property, durability or the like and provided with economical property, may be obtained.

摘要： PURPOSE:To easily and efficiently remove cobalt in an aq. nickel salt soln. by bringing the aq. nickel salt soln. contg. cobalt ion as an impurity into contact with an adsorbent consisting of a synthetic porous multicomponent oxide. CONSTITUTION:An aq. soln. of a nickel salt (e.g. nickel sulfate) contg. cobalt ion as impurity is brought into contact with an adsorbent consisting of a synthetic porous multicomponent oxide to adsorb cobalt ion, and the cobalt ion in the soln. is removed. A silica-titania-based multicomponent oxide, a silica- magnesia-based multicomponent oxide contg. silica and magnesia in (75:25) to (0:100) weight ratio, etc., are exemplified as the oxide. The adsorbent consisting of a silica-titania-based multicomponent oxide is obtained, for example, by adding aq. ammonia to an aq. soln. contg. titanium tetrachloride and silicon tetrachloride and calcining the precipitate.

摘要： PURPOSE: To obtain electrically conductive stannic oxide having excellent electrical conductivity and suitable as an antistatic agent for synthetic fiber, by dispersing antimony oxide in an aqueous solution of tartaric acid, mixing the dispersion with hydrated stannic oxide, and drying, pulverizing and calcining the mixture.
CONSTITUTION: Antimony tartrate is produced by dispersing antimony oxide in an aqueous solution of tartaric acid. The amount of tartaric acid is ≥0.01 equivalent per 1 equivalent of antimony. Hydrated stannic oxide is added to the dispersion, mixed thoroughly with a ball mill, etc., dried in a hot-air circulation drier, etc., pulverized with an impact pulverizer, and calcined with a calcination oven to obtain the objective electrically conductive stannic oxide wherein a part of Sn atoms of stannic oxide are substituted with Sb atoms. A product having excellent electrical conductivity can be produced without using the water-washing step, even at a calcination temperature of as low as ≤1,000°C, and accordingly, the compound can be obtained at a low cost with simple procedure.
