Abstract: There is disclosed a method for making a self-supporting ceramic composite article having a porous core bearing a dense surface layer formed integrally with said core. A preform comprises a filler material and parent metal distributed therethrough, wherein the volume percent of parent metal is sufficient to form a volume of oxidation reaction product exceeding the total volume available within said preform. The parent metal is melted and reacted with an oxidant to form an oxidation reaction product filling the spatial volume and leaving voids. The reaction is continued to further transport molten parent metal through the oxidation reaction product to at least one surface of the preform to form oxidation reaction product on said surface substantially free of voids thereby forming a relatively dense surface layer.

Abstract: A titanium nitride coating is applied over the cubic boron nitride layer of conventional CBN tools by the process of arc physical-vapor-deposition at temperatures below the tempering temperature of the core metal. The titanium nitride coating stabilizes and reinforces the existing bond between the cubic boron nitride and the core, resulting in a grinding tool with greater efficiency and longer life. Specific operating conditions are required during the deposition process in order to ensure the proper level of adhesion of the titanium nitride layer.

Abstract: A semiconductor wafer polishing slurry that does not contaminate a wafer processing area utilizes an aqueous organic base to suspend the slurry's fine abrasive particles. The organic base has large cations (13,16,19) that do not diffuse into semiconductor wafers. Therefore ionic contamination from the polishing slurry is substantially eliminated.

Abstract: A print of this invention has a color-forming area and a discoloring area.

Abstract: A Group IIA metal-Group IIIA metal-silicon substantially homogeneous liquid alkoxide is prepared from a reaction mixture of a Group IIA metal, a Group IIIA metal, a silicon tetraalkoxide, and a liquid defined by the formula ROR' where R is an alkyl group and R' is hydrogen or an alkyl group. The alkoxide can then be hydrolyzed, azeotropically distilled, dried, milled, and calcined to produce a ceramic powder. Advantageously, the ceramic powder can be compacted and sintered at relatively low temperatures which enable it to be used in electrical applications where high sintering temperatures would be deleterious.

Abstract: A composite yet monolithic free abrasive grinding lap includes a sintered porous matrix of ceramic or metal material and a quantity of silicon filler material, substantially completely filling the pores of the sintered porous matrix preform at least throughout an effective region of the lap that is to come in contact with a workpiece to be acted upon by the lap. The lap may further have a multitude of abrasive particles embedded in the filler material at the effective region. The lap is made by first slip-casting a preform, then freezing and freeze-drying the same, followed by lightly sintering the dry preform into a porous matrix preform, bringing the temperature of the preform to above the melting point of the silicon filling material, and filling the pores with the filling material in its molten state.

Abstract: Thermodynamically stable ceramic composites are provided for use in high temperature oxidizing environments. The composites comprise high strength alumina fibers (Al.sub.2 O.sub.3) in a ceramic matrix. The ceramic matrix comprises material similar to the fibers to improve compatibility of the composite materials. A material selected from the .beta.-alumina and magnetoplumbite family of materials is used to provide a weakly bonded interface between the fibers and the ceramic matrix. .beta.-aluminas and magnetoplumbites have weak layers as an intrinsic characteristic of their crystal structure, which comprise spinel layers (basically Al.sub.2 O.sub.3) separated by very weakly bonded planes containing the .beta.-forming ions. The weak planes of these materials allow preferential debonding and sliding, and thus inhibit crack growth across the interface between the fibers and the ceramic matrix. The alumina fibers can be coated with .beta.
