A method of forming a porous ceramic article having a narrow pore distribution includes heating a green body containing ceramic forming raw materials in a firing environment that raising the temperature of the firing environment to a peak temperature, then reducing the temperature to a hold temperature in order to form porous ceramic.

Method of firing green bodies into porous ceramic articles

A method for manufacturing a honeycomb structure comprises providing an aqueous ceramic solution, providing a batch cross-link agent, mixing the agent with the solution, extruding the aqueous ceramic solution containing the cross-link agent into a honeycomb structure, and drying the honeycomb structure via a single drying step thereby forming a hardened, substantially water resistant, honeycomb structure. The method may further comprise addition of a ceramic surfactant to the aqueous ceramic solution, as well as plugging channels within the honeycomb structure with a plugging material comprising an aqueous ceramic solution that includes batch cross-link agents and ceramic surfactants therein. Also disclosed is a green body honeycomb article having a green honeycomb matrix containing a first ceramic batch compound of inorganic constituents, a first batch cross-link agent, and an aqueous vehicle wherein the matrix includes interconnected walls forming open-ended channels and a plugging material located in at least one of the open-ended channels.

A method for fabricating optical devices for transmission and/or manipulation of light includes steps of providing a substrate which defines a reference plane for positioning cladding material and core material, fixing rigid spacers to an upper surface of the substrate, the spacers having upper surfaces which define a second plane spaced above the reference plane, depositing a layer of a formable, curable under-cladding material over the upper surface of the substrate, the upper surface of the rigid spacers providing a guide for precise control of the height of the under-cladding material above the surface of the substrate, curing the under-cladding material under compression to form an under-cladding layer, and depositing a light guide core and over-cladding on the under-cladding. The method is susceptible to mass production and provides more precise control of the position of the light guide core relative to a substrate surface. The resulting optical device includes a substrate, a pattern of rigid spacers fixed to the upper surface of the substrate, a polymeric under-cladding layer positioned on the substrate and in space defined between the rigid spacers, a polymer light guide core positioned on the under-cladding layer, and a polymeric over-cladding layer positioned over the light guide core and at least a portion of the under-cladding.
