    摘要: A disclosed ceramic honeycomb catalyst having an excellent thermal shock resistance in which a carrier is coated on a ceramic honeycomb structural body, has a mean thermal expansion coefficient in a range from 40 to 800 °C of smaller than 0.7x10 -6 /°C. Therefore, it is possible to obtain a ceramic honeycomb catalyst having an excellent thermal shock resistance in which a mechanical strength of a ceramic honeycomb structural body to which a carrier such as γ-alumina is coated is not decreased and the carrier is not peeled off from the ceramic honeycomb structural body.

    摘要: A method of producing a porous ceramic filter, using a cordierite composition including a talc powder component and a silica powder component, such that particles of the talc power component and the silica powder component whose size is not less than 150µm constitute not more than 3% by weight of the cordierite composition, while particles of the talc and silica powder components whose size is not more than 45µm constitute not more than 25% by weight of the cordierite composition. A green body for the porous ceramic honeycomb filter formed of this cordierite composition is fired into the desired porous ceramic honeycomb filter.
