摘要:
A ceramic plate structure includes a first transmittance-enhancing film layer disposed between a substrate and a first binding film layer, a conductive film layer disposed between the first binding film layer and a second binding film layer, and a second transmittance-enhancing film layer disposed between the second binding film layer and a ceramic layer. The ceramic layer renders the ceramic plate structure satisfactory in terms of transmittance gain, thermal conductivity coefficient, electrical insulation, rigidity, resistance to wear and tear, and resistance to wind erosion of the ceramic plate structure. The ceramic plate structure is suitable for use with touch panels to therefore enhance the cost-effectiveness of the manufacturing process of touch panels by cutting its material costs, reducing its power consumption, and shortening its production cycle. Accordingly, the anticipated benefits and objectives of the ceramic plate structure are attained.

A honeycomb structure body having joining material layers of a stress relaxing function and joining strength equivalent to those of joining material layers of a conventional honeycomb structure body, and having an excellent heat shock resistance. A honeycomb structure body includes a plurality of honeycomb segments and joining material layers having a plurality of pores and joining the plurality of honeycomb segments in a state where the honeycomb segments are arranged adjacent to each other so that side surfaces of the honeycomb segments face each other. A ratio of the number of pores having a value of 1.2 or less which is obtained by dividing a maximum diameter of each of the pores by a minimum diameter of the each of the pores is 60% or more of the number of all the pores of each of the joining material layers.

Diamond bonded constructions comprise a body comprising a plurality of bonded together diamond grains with interstitial regions disposed between the grains that are substantially free of the catalyst material used to initially sinter the body. A metallic substrate is attached to the body, and a braze joint is interposed between the body and the substrate. The body is metallized to include a metallic material disposed along a substrate attachment surface in contact with the braze joint, wherein the metallic material is different from the braze joint material. The metallic material may exist within a region of the body extending fully or partially into the body, and/or may exist as a layer extending away from the substrate attachment surface. The body includes a working surface characterized by empty interstitial regions or by interstitial regions filled with an infiltrant material, wherein the infiltrant material is different from the metallizing material.

In one embodiment, a joint between first and second articles each comprising a ceramic polymorph comprises a matrix comprising the ceramic polymorph and extending between the first and second articles; a plurality of inclusions comprising the ceramic polymorph and being distributed throughout the matrix; and a sealing layer comprising the ceramic polymorph and being respectively disposed on the first and second articles and the matrix.
摘要:
A ceramic honeycomb structure comprised of at least two separate smaller ceramic honeycombs that have been adhered together by a cement comprised of inorganic fibers and a binding phase wherein the smaller honey-combs and fibers are bonded together by the binding phase which is comprised of an silicate, aluminate or alumino-silicate. The fibers have a multi-modal size distribution in which some fibers have lengths of up to 1000 micons and other fibers have lengths in excess of 1 mm. The cement composition may be made in the absence of other inorganic and organic additives while achieving a shear thinning cement, for example, by mixing oppositely charged inorganic binders in water together so as to make a useful cement composition for applying to the smaller honeycombs to be cemented.
