  • Oxide ion conductor
    Patent number: 7682528
    Abstract: An La2O3 powder and an SiO2 powder are mixed with each other, and then heated. By heating, a porous material of LaXSi6O1.5X+12 (8?X?10) as a composite oxide is produced. Subsequently, the porous material is pulverized to obtain a powder, and the powder is added to a solvent to prepare a slurry. The slurry is solidified in a magnetic field to prepare a compact. After that, the compact is sintered, and an oxide ion conductor is obtained thereby.
    Type: Grant
    Filed: September 18, 2006
    Date of Patent: March 23, 2010
    Assignee: Honda Motor Co., Ltd.
    Inventors: Yoshikatsu Higuchi, Masayuki Sugawara, Kagehisa Hamazaki, Keizo Uematsu, Susumu Nakayama

  • Oxide ion conductor and method of producing the same
    Publication number: 20040161651
    Abstract: An La2O3 powder and an SiO2 powder are mixed with each other, and then heated. By heating, a porous material of LaXSi6O1.5X+12 (8≦X≦10) as a composite oxide is produced. Subsequently, the porous material is pulverized to obtain a powder, and the powder is added to a solvent to prepare a slurry. The slurry is solidified in a magnetic field to prepare a compact. After that, the compact is sintered, and an oxide ion conductor is obtained thereby.

  • Observing techniques and its evaluation equipments of filler packing-structure for resin polymer composite filled with ceramic filler-powder
    Patent number: 6747739
    Abstract: This invention relates to a method of measuring the internal structure (packing structure or dispersion condition of particulate material) of a composite filled with particles having an irregular matrix by observations based on its optical anisotropy, in which the internal structure (packing structure or dispersion condition of particulate material) of the composite obtained by mixing particulate material as raw material with a liquid material is made visible by utilizing the photoelasticity based on local rearrangement of liquid material molecules or difference of refractive indices of the particulate material and liquid material, and the structure thereof are observed, and an evaluation device using this principle of measurement.
