    • PURPOSE:To obtain an easily portable and conveniently usable solid agent for generating oxygen which generates oxygen by the contact with water with good durability by mixing an inorg. peroxide with expanded graphite having low density together with a neutralizing agent and catalyst, and transforming the mixture to a solid shape. CONSTITUTION:An inorg. peroxide (e.g. barium peroxide, calcium peroxide), a neutralizing agent (e.g. primary calcium phosphate, calcined gypsum), and catalyst (e.g. MnO2) are mixed with low density expanded graphite, and the mixture is transformed to solid to obtain the target solid agent for generating oxygen. Said low density expanded graphite is obtd. by expanding graphite. When the solid agent is to be used, the agent is allowed to contact with water, thus reactions expressed by the formulas I, II proceed gradually generating oxygen. Further, since a strongly alkaline substance is also generated at the same time with the generation of oxygen, the reaction product is neutralized with the generation of oxygen, the reaction product is neutralized with a neutralizing agent contained in the solid agent. The obtd. solid agent for generating oxygen is pref. used fro the transportation of fishes, recovery from fatigue after sports, etc.

    • PURPOSE: To provide a metal oxide complex composed mainly of oxides of Ce, Bi and Co, and capable of separating high purity oxygen from an oxygen-containing gas.
      CONSTITUTION: Oxides of Ce, Bi and Co, e.g. CeO
      2 , Bi
      2 O
      3 and Co(OAc)
      2 4H
      2 O, ar crushed, mixed together, calcined in air, and crushed again. The powder is compression molded and calcined in air to obtain a metal oxide complex. The number of Ce and Bi atoms in the complex is 0.3W15g-atom each per 1g-atom of Co. The complex has an electron conductivity of ≥1×10
      -2 Ω
      -1 cm
      -1 and an oxygen ion conductivity of ≥1×10
      -4 Ω
      -1 cm
      -1 . When two airtight chambers are placed at both sides of a layer composed of the complex, and the oxygen partial pressure in one of the chamber is made higher than that in the other chamber, oxygen is separated to the chamber having lower oxygen partial pressure.
