摘要： PROBLEM TO BE SOLVED: To provide a needle-like ceramic body comprised of a cordierite porous body that is stable at high temperatures and has a large specific surface area as a base material and a needle-like ceramic catalyst body and a method for producing the same. SOLUTION: The needle-shaped ceramic body comprises the cordierite porous body that is composed of a porous structure of prescribed porosity formed with needle-like cordierite crystal phase and is stable at the high temperatures and has the large specific surface area as the base material. The needle-shaped ceramic catalyst body is formed by supporting a catalyst component on the ceramic body. By using the porous cordierite composed of needle-like crystals as a catalyst-supporting honeycomb structure, a decrease in the specific surface area caused by sintering can be suppressed. Since a honeycomb structure can be directly produced from a cordierite sintered body by itself, a low-cost product can be obtained by omitting a step for coating the inside of the honeycomb structure in the conventional process.

摘要： PROBLEM TO BE SOLVED: To provide a ceramic carrier having a cordierite porous body, which is stable at high temperature and has high specific surface area, as a base material and a granular agglomerate in which fibrous ceramics are intertwined with one another and to provide a ceramic catalytic body. SOLUTION: The cordierite-based porous ceramic carrier has the granular agglomerate in which fibrous ceramics are intermingled with one another. The ceramic catalytic body is manufactured by depositing a catalyst component on the porous ceramic carrier and has fibrous ceramics. A method for manufacturing the porous ceramic carrier comprises a step of reacting a part of a raw material with a porogen to produce the granular agglomerate of fibrous ceramics intermingled with one another on the surface of a sintered compact at a firing step. As a result, a catalyst-deposited honeycomb structure can be obtained, which has large specific surface area, the decrease of whose specific surface area due to the sintering is restrained, which has a small heat capacity and consequently is activated in early stages and has a small pressure loss, the cordierite porous body as the base material and the granular agglomerate of fibrous ceramics intermingled with one another.

摘要： PROBLEM TO BE SOLVED: To provide a silicon nitride ceramic having a high temperature corrosion resistant coating film and its manufacturing method. SOLUTION: The silicon nitride ceramic has a rare earth titanate as the high temperature corrosion resistant layer on the surface thereof in which a rare earth silicate is contained by volume ratio of 1:(0-0.7) as a material for forming a multi-phase and has a rare earth silicate as a bonding layer for the silicon nitride ceramic and the high temperature corrosion resistant layer. As a result, the silicon nitride ceramic has excellent high temperature steam corrosion resistance at a high temperature of ≥1,100°C. The high temperature corrosion resistant layer is durable for a long time even when the film is thin because there is no wear of the coating film due to corrosion and exhibits self-repairing function even if crack is produced on the coating film by accident by giving a rare earth enriched rare earth titanate composition to the coating film.
