Two or more kinds of components selected from 6pts. or less of Fe2O3, 3pts. or less of MnO2, 6pts.wt. or less CoO and 3pts. or less of TiO2 are compounded in 100pts. of the prepared composition in a total amount of 12pts. or less. The resulting composition is molded by an extrusion molding method and baked at 1,350-1,450 deg.C to prepare a purification catalyst carrier for combustion machinery with thermal expansion coefficient of 16X10 / deg.C or less.

摘要： PURPOSE:To obtain high heat insulating property with a simple construction by constituting a jointing interface of both materials with partial contacted faces and air heat insulating layers, in an enveloping cast with a metallic body on the outer surface of a ceramic liner contacted with exhaust gas. CONSTITUTION:In an internal combustion engine, an exhaust manifold consists of a ceramic liner 1 made from aluminum titanate series ceramic having Young' s modulus under 2000kgf/mm and a metallic body 2 integrally casting the outer surface of the ceramic liner with aluminum alloy or the like. And in this case, the jointing interface between the ceramic liner 1 and the metallic body 2 consists of partial contacted surfaces 3 directly contacting the ceramic liner 1 with the metallic body 2, and air heat insulating layers 4 without contact of both. Moreover the shape of the contacted surfaces 3 are formed arbitrarily such as in line, spiral, dot-like, and the like.

摘要： PURPOSE:To provide a heat exchange body which has excellent heat exchange efficiency, is decreased in a pressure loss, and has excellent thermal shock resistance, by a method wherein a matrix segment having a crystal phase consisting mainly of cordierite and honeycomb structure having a specific coefficient of thermal expansion is extrusion-molded, and after calcination, a given ceramic cementing material is coated for cementing, and thereafter it is dried and calcined. CONSTITUTION:A cordierite material having the coefficient of thermal expansion being as low as 0.06% or less in the direction of a flow passage at up to 800 deg.C is molded to form a matrix segment having honeycomb structure formed in cell shape, e.g. a triangle, a square, and a hexagon, by an extrusion-molding method and is calcined. By using a plurality of matrix segments 1, the segments 1 are processed so as to form an integral rotary heat accumulation type ceramic heat exchange body 2. A ceramic cementing material having a chemical composition consisting mainly of LiO2, Al2O3, SiO2 and a crystal phase consisting mainly of beta-spodumene solid solution is coated and cemented so that thickness after calcination will be 0.1-6mm. After it is dried enough it is calcined under conditions of 1,250-1,320 deg.C and 15-90min to obtain a rotary heat accumulation type ceramic heat exchange body.

摘要： PURPOSE:To reduce the thermal expansion coefficient and to enhance the resistance to thermal shock of the titled catalytic body by depositing a catalytic component on a cordierite ceramic honeycomb structure which has been treated with an acid and then heat-treated at 600-1,000 deg.C. CONSTITUTION:A cordierite ceramic honeycomb structure is treated with an acid. In the acid treatment, a mineral acid such as HCl and H2SO4 is preferably used in consideration of the cost, a 1-5N acid is used and the treatment is preferably carried out at about 50-100 deg.C. Consequently, a structure having >=5m /g specific surface, >=100kg/cm compressive strength and / deg.C thermal expansion coefficient at 40-80 deg.C is obtained. The structure is heat- treated at 600-1,000 deg.C and then a metallic catalytic component such as Pt, Pd and Rh is deposited. Meanwhile, the catalytic component can be deposited after acid treatment, then the structure is heat-treated at 600-1,000 deg.C and the same objective can be achieved.
