Abstract: A plate (10) for use in mixing and testing materials in the pharmaceutical industry is formed by a method in which apertures (22) (24) in a set of greensheets are formed by a material removal process, at least some of the apertures (25) being filled with a fugitive material (222) that escapes during sintering.

Abstract: Disclosed is an aluminum nitride body having graded metallurgy and a method for making such a body. The aluminum nitride body has at least one via and includes a first layer in direct contact with the aluminum nitride body and a second layer in direct contact with, and that completely encapsulates, the first layer. The first layer includes 30 to 60 volume percent aluminum nitride and 40 to 70 volume percent tungsten and/or molybdenum while the second layer includes 90 to 100 volume percent of tungsten and/or molybdenum and 0 to 10 volume percent of aluminum nitride.

Abstract: FI9-90-027 COPPER-BASED PASTE CONTAINING COPPER ALUMINATE FOR MICROSTRUCTURAL AND SHRINKAGE CONTROL OF COPPER-FILLED VIAS A copper-based paste is disclosed for filling vias in, and forming conductive surface patterns on, ceramic substrate packages for semiconductor chip devices. The paste contains copper aluminate powder in proper particle size and weight proportion to achieve grain size and shrinkage control of the via and thick film copper produced by sintering. The shrinkage of the copper material during sintering is closely matched to that of the ceramic substrate.
