Abstract: PURPOSE:To obtain the subject superconductor having excellent characteristics by heat treating a mixed powder containing a specified powder and having a composition of the above-mentioned oxide superconductor at a prescribed and comparatively low temperature for a comparatively short time. CONSTITUTION:A solid phase (e.g. Y2O3) existing together with a liquid phase when a Y-based oxide superconductor (e.g. Y-Ba-Cu-O-based oxide) is heated at >= a prescribed temperature is used as the core and the core is covered with a substance (e.g. BaCuO2) containing elements capable of a reaction with the above-mentioned core and production of the above-mentioned oxide superconductor thereby. The above obtained powder is then blended with another powder and the resultant mixed powder (e.g. mixed powder containing both BaCuO2 powder and CuO powder) containing the above-mentioned powder and having the composition of the above-mentioned oxide superconductor is heat treated at a temperature in the neighborhood of the melting point of the above- mentioned covering material.

Abstract: PURPOSE:To evaluate kneading property, by measuring specified amounts of resin and ceramic powder to be used before injection molding, inputting the resin and the ceramic powder in a rotary viscosimeter, which is kept at a specified temperature, kneading them at a specified number of rotations, and measuring the duration of the maximum fluctuation width of the rotary torque. CONSTITUTION:Ceramic powder and a resin are kneaded, and a required molded product is manufactured by injection molding. Before manufacture, specified amounts of the resin and the ceramic powder to be used are measured and put into a rotary viscosimeter, which is kept at a specified temperature. They are kneaded at a specified number of rotations. After the start of kneading, the time period, during which the fluctuation width of the rotary torque value keeps the maximum value, is measured. Based on the measured time period, the kneading property of the ceramic powder and the resin used for the injection molding is evaluated. The kneading property of the ceramic powder and the resin is accurately evaluated before the kneading. Thus the fluidic molding pressure of the kneaded material can be accurately controlled.

Abstract: PROBLEM TO BE SOLVED: To provide a hydrogen generation structure improved in the efficiency of transmitting hydrogen and to obtain a reforming composite material improved in the efficiency of a reforming reaction. SOLUTION: An adsorption/reforming layer 11 is porous and is constituted of a porous substrate having through-holes having a diameter larger than that of a pore. Fine ceramic particles 20 that constitute the porous substrate exist within the layer 11. A number of pores 21 having a pore diameter of 0.5-5 nm are formed on the surface of each ceramic particle. The ceramic particles 20 are arranged at intervals of several to several tens μm, and the continuations of these gaps form through-holes 22. Each pore 21 has the function of concentrating methane by adsorbing and condensing a natural gas as the starting gas, and the through-holes 22 have the function of diminishing the pressure loss of the natural gas across the layer 11.

Abstract: PROBLEM TO BE SOLVED: To provide a producing method of amorphous silica particles which have low production cost and high sphericity. SOLUTION: This producing method of amorphous silica particles is featured by comprising a stage of supplying raw material which supplies silicon powder and silica powder together with a carrier gas into a reaction chamber, a burning and heating stage of burning the supplied silicon powder in the reaction chamber, generating heat, heating the resultant silica and the silica powder and dissolving or vaporizing the same and a cooling stage of cooling the dissolved and vaporized silica and forming the amorphous silica particles. Therein, the silica is made to a complete sphere owing to the surface tension by melting and is made to the amorphous silica particles having high sphericity by being cooled as it is. Further, by being vaporized once, the silica is made to the amorphous silica having high sphericity when cooled and flocculated.

The oxide of the metal and the coating film preferably comprise Al2O3 and AlN, respectively, and the oxide of the metal and the coating film further preferably comprise SiO2 and Si3N4, respectively. A ratio of the thickness of the coating film to the radials of the particles is 0.05 to 0.6. The powder can be obtained by nitriding the oxide of the metal. It is preferable that the heat conductivity of the obtained powder is equal to that of the coating film.
