摘要： In a method of baking a ceramic honeycomb structure, when baking a honeycomb formed body having an apparent volume equal to or more than five liters, the speed of temperature rise in a baking atmosphere from the temperature (180-300°C) at which an organic binder contained in the honeycomb structure starts to burn up to 300°C is equal to or more than +25 (°C/hour). Further, the speed of temperature rise is such that the difference between the temperature at the center portion of the honeycomb formed body and the temperature of baking atmosphere is maintained in a predetermined range.

摘要： A sealed honeycomb structure (1) and a method of producing the honeycomb structure, where the honeycomb structure has partition walls (2) arranged so as to form cells (3) axially penetrating from one end face (42) to the other end face (44) and sealing portions (4) arranged so as to seal each cell (3) at either end. In the honeycomb structure (1), a sealing portion (4) and surrounding partition walls are united to each other. The producing method includes a forming step, a sealing step for charging a sealing agent, and a firing step. The sealing agent contains solid grains capable of uniting with at least a kind of solid grain contained in a raw material for forming. In the firing step, the ratio of a dimensional change occurring when the partition walls are formed from partition wall forming bodies surrounding the sealing portions to a dimensional change occurring when the sealing portions are formed from the sealing agent. The ratio is controlled to be 0.7-1.3. In the structure above, the strength between the partition walls and the sealing portions is increased, and adhesiveness and thermal shock resistance are improved.

摘要： A honeycomb ceramic structure which has a chemical composition: SiO2: 42 to 56 %, Al2O3 : 30 to 40 %, and MgO: 12 to 16 wt %, and has a crystal phase comprising cordierite as a main phase, characterized in that it has a porosity of 55 to 65 % and an average pore diameter of 15 to 30 µm, and a total area of the pores exposed on the surface of the partition walls constituting the honeycomb ceramic structure is 35 % or more relative to the total surface area of the partition walls; and a method for preparing the honeycomb ceramic structure which comprises adding, to raw materials for a cordierite ceramic, 15 to 25 wt % of graphite and 5 to 15 % of a synthetic resin as agents for making pores, kneading the resulting mixture, and forming it into a honeycomb structure, followed by drying and firing. The honeycomb ceramic structure allows the achievement of high capturing efficiency together with low pressure loss.
