Abstract: An improved method for injection molding fine particulate inorganic materials that first spray dries a fine particulate inorganic material and then mixes the dried particulate inorganic material with a binder system to form a compounded material. The compounded material is then injected, at a low pressure into a mold to form a green part. The green part is then debinded to remove most of the binder system and the debinded green part is then sintered to form the final molded part.

Abstract: Ceramic guide rails for guiding photographic film into a perforating machine are disclosed. The ceramic includes zirconium oxide and yttria in a molar ratio of yttria to zirconium oxide of from about 3:97 to about 5:95. The zirconium oxide is essentially the tetragonal phase crystal grain. In an alternate embodiment of the present invention the outer surface of the zirconium oxide is altered to the cubic phase crystal grain or the monoclinic crystal grain.

Abstract: Lithographic printing is carried out by a novel process utilizing a zirconia ceramic as a printing plate. In this process, the surface of the zirconia ceramic printing plate is imagewise exposed to radiation which transforms it from a hydrophilic to an oleophilic state or from an oleophilic to a hydrophilic state, thereby creating a lithographic printing surface which is hydrophilic in non-image areas and is oleophilic and thus capable of accepting printing ink in image areas. The zirconia ceramic printing plate utilized in this process is capable of extremely long printing runs, is especially well adapted for direct digital laser imaging using images that are electronically captured and digitally stored, and can be reused by erasing the image from the ceramic surface by thermally-activated oxidation or laser-assisted oxidation.

Abstract: A functionally gradient permanent magnet is formed as a slab of alloy comprised of a rare earth-transition metal-boron, and areas of a diffused transition metal positioned at points along the length of at least one surface of the slab of alloy.

Abstract: A method for preparing a ceramic article comprising compacting a particulate alloy of a primary oxide and a secondary oxide to form a blank, and sintering the blank in contact with substantially pure zirconium oxide. The primary oxide is zirconium oxide and the secondary oxide is selected from the group consisting of MgO, CaO, Y.sub.2 O.sub.3, Sc.sub.2 O.sub.3, rare earth oxides and combinations thereof. Ceramic articles produced have tetragonal phase cores and monoclinic cases.

Abstract: Micro-electromechanical ceramic parts are formed using green ceramic and a sacrificial material that has a higher melting temperature than the sintering temperature of the green ceramic to form electrical trace paths. After the sintering of the ceramic part the sacrificial material is removed by etching or by elevating the temperature of the part above the melting temperature of the sacrificial material. The void left by the removal of the sacrificial material is then filled with a molten metal which when cooled forms the electrical trace for the fabricated part.
