摘要:
A honeycomb structure body which has a number of passages partitioned with partition walls and penetrating along the axial direction. A porous honeycomb structure body which contains refractory grains as filler, one or more elements selected from the group consisting of the rare earth elements, alkaline earth elements, Al, and Si, and the crystal containing one or more kinds of these elements. The present honeycomb structure body contains refractory grains such as silicon carbide grains and the like, but it can be produced at a relatively low firing temperature at a low price, it is sufficiently porous and high in specific surface area, and it can be used as a filter for purifying automobile exhaust gas, a catalyst carrier, and the like under the high SV conditions.
摘要:
A honeycomb structure made of a silicon carbide-based porous body and having a number of through-holes extending in the axial direction, separated by partition walls. The strength and Young's modulus of the silicon carbide-based porous body satisfy the following relation: Strength (MPa)/Young's modulus (GPa)≧1.1. The honeycomb structure contains refractory particles such as silicon carbide particles and the like and yet can be produced at a relatively low firing temperature at a low cost, has a high strength and a high thermal shock resistance, and can be suitably used, for example, as a filter for purification of automobile exhaust gas by a treatment such as plugging of through-channel at its inlet or outlet, or as a catalyst carrier, even under a high SV condition.

There is provided a joined body formed by unitarily joining two or more members to be joined by means of a bonding material layer formed of a bonding material composition. The bonding material composition contains flat particles, non-flat particles, and an inorganic adhesive as main components, and the bonding material layer has a Young's modulus of 3 GPa or more. The joined body can suppress deformation of members to be joined due to thermal distortion with the bonding material layer, hardly causes rupture of the bonding material layer due to stress, and has excellent thermal shock resistance.

A highly heat-conductive Si-containing material containing a Si phase whose lattice constant at room temperature is controlled at a level of more than 0.54302 nm but 0.54311 nm or less. Firing is conducted using a kiln material containing no B compound. With this highly heat-conductive Si-containing material and the process for production thereof, a reduction in heat conductivity can be prevented and a high heat conductivity can be exhibited stably.
