20080248238 | BONDING MATERIAL, PROCESS FOR PRODUCING THE SAME, AND HONEYCOMB STRUCTURE MADE WITH THE SAME - There is provided bonding material having a Young's Modulus after hardening of not less than 20% of articles to be bonded, and an average linear coefficient of thermal expansion after hardening of not more than 70% of the articles to be bonded. This bonding material can suppress deformation of a honeycomb segment due to thermal stress to be generated by a bonding material layer and can suitably be used at the time of manufacturing exhaust gas trapping filters capable of reducing the generation of defects such as a crack, and above all, a diesel particulate filter (DPF) for trapping particulate matter (particulates) in exhaust gas from the diesel engine. | 10-09-2008 |
20090022943 | BONDED BODY, BONDING MATERIAL COMPOSITION, HONEYCOMB SEGMENT BONDED BODY, AND HONEYCOMB STRUCTURE USING THE SAME - There is provided a bonding material composition capable of suppressing crack generation on an end face of a resultant honeycomb structure to a large extent by reducing anisotropy of Young's modulus after curing of the bonding material by the use of an isotropic filler without using inorganic fibers. The bonded body has two or more members unitarily bonded by means of a bonding material layer, and the relational expression of 0.501-22-2009 | |
20090041975 | BONDED ELEMENT, HONEYCOMB SEGMENT BONDED ELEMENT, AND HONEYCOMB STRUCTURE USING THE SAME - There is disclosed a bonded element manufactured from a bonding material composition being capable of contributing to the lowering of thermal expansion of a bonding material layer sufficiently to relax any thermal stress generated in a honeycomb structure and largely inhibiting the cracking of the resultant honeycomb structure as well. In a bonded element in which two or more objects to be bonded are integrated via a bonding material layer, the bonding material layer having a Young's modulus of 20% or less of that of the objects to be bonded and having an average linear thermal expansion coefficient of 70% or less of that of the objects to be bonded, the bonding material layer being prepared from a bonding material composition composed mainly of fillers and a matrix in which fillers having an average linear thermal expansion coefficient of 2.0×10 | 02-12-2009 |
20090176043 | SILICON CARBIDE BASED POROUS MATERIAL AND METHOD FOR PREPARATION THEREOF - A silicon carbide based porous material, which contains a metal silicide in an amount of 1 to 30% by mass and having a porosity of 38 to 80%, is provided. | 07-09-2009 |
20090214819 | CERAMIC KNEADED CLAY AND USAGE THEREOF - An oxide-ceramic forming clay comprising an oxide-ceramic forming material, a layered double hydroxide, a pore-forming agent, and water, wherein the amount of the pore-forming agent is between 3 and 50 parts by mass by superaddition to 100 parts by mass of a sum of the oxide-ceramic forming material and the layered double hydroxide and a sum of the pore-forming agent and an organic binder is between 5 and 55 parts by mass also by superaddition which has environment-friendly characteristics in a forming firing step, and usage thereof. | 08-27-2009 |
20100243557 | ALUMINA POROUS BODY AND METHOD OF PRODUCING THE SAME - An alumina porous body has a porosity of 15 to 45% and an average pore size of 2 to 15 μm includes 5 to 30 mass % of titanium oxide and at least one element selected from the group consisting of copper, manganese, calcium, and strontium, the total content of oxides of the at least one element being 1.5 mass % or less. | 09-30-2010 |
20110244176 | CERAMIC CLAY, CERAMIC FORMED ARTICLE, AND CERAMIC STRUCTURE, AND MANUFACTURING METHODS THEREOF - The ceramic clay is available by kneading a forming raw material containing a ceramic forming material. The forming raw material contains, in addition to the ceramic forming material, a layered double hydroxide represented by a predetermined chemical formula in an amount of from 0.01 to 5 mass % based on the total amount of them. The layered double hydroxide turns into a gel by dispersing it in water and when it is dispersed in water at a concentration of 6 mass %, it has a viscosity of from 1000 to 20000 mPa·s. | 10-06-2011 |
20140113106 | METHOD OF MANUFACTURING HONEYCOMB STRUCTURE AND HONEYCOMB STRUCTURE - A honeycomb structure mainly composed of cordierite and obtained by forming and firing a forming material containing a layered clay mineral whose layer charge (X) is 0.204-24-2014 | |
