  • Needle-shaped ceramic body, needle-shaped ceramic catalyst body and method for producing same
    Patent number: 7855162
    Abstract: The present invention provides a needle-shaped ceramic body and needle-shaped ceramic catalyst body in which a base material is a high specific surface area porous cordierite body that is stable at high temperatures, and also provides methods of producing this needle-shaped ceramic body and needle-shaped ceramic catalyst body. The present invention relates to a needle-shaped ceramic body and needle-shaped ceramic catalyst body in which a base material is a high temperature-stable, high specific surface area porous cordierite body comprising a porous structure having a prescribed porosity and formed of a needle-shaped cordierite crystal phase, and further relates to methods of producing this needle-shaped ceramic body and needle-shaped ceramic catalyst body, and by using porous cordierite constituted of needle-shaped crystals as a catalyst-supporting honeycomb structure, the present invention is able to inhibit sintering-induced reduction in the specific surface area.

  • Ceramic support capable of supporting catalyst, catalyst-ceramic body and processes for producing same
    Patent number: 7838462
    Abstract: A needle-shaped ceramic body having as its base material a cordierite porous body having a high specific surface area and superior thermal shock resistance, and a needle-shaped catalyst-ceramic body are provided. The present invention relates to a needle-shaped ceramic body having as its base material a needle-shaped cordierite in which the tips thereof are rounded, a needle-shaped catalyst-ceramic body loaded with a catalyst, and a method of production of a ceramic body in which a portion of a raw material (fluoride) gasified by a reaction between raw materials is grown into a needle like shape on the metal catalyst (Fe), wherein the tips of needle-shaped particles are rounded, using a vapor-liquid-solid (VLS) reaction, in a raw material burning process.

  • Environmental barrier coating material and coating structure and ceramic structure using the same
    Patent number: 7138183
    Abstract: An environmental barrier coating material comprising one or more constituents selected from a group consisting of hafnia; hafnia stabilized by one or more rare-earth oxides and/or silica; zirconia-containing hafnia; and zirconia-containing hafnia stabilized by one or more rare-earth oxides and/or silica, which when formed as a coating structure for covering a substrate which has a low thermal expansion coefficient, has hafnon (HfSiO4) serving as a first layer directly formed on the substrate, and hafnia with which the first layer is coated as a second layer.
