  • Patent number: 5250251
    Abstract: A process for shaping parts from ceramic powder that comprises the steps of (1) forming a concentrated mixture in excess of 40% ceramic solids by volume, the mixture comprising ceramic powder, a gel forming material chosen from the class of polysaccharides known as "agaroids", and a gel forming material solvent and being formed in a blender that provides a shearing action and is heated to raise the temperature of the mixture to about 70.degree. C. to 100.degree. C.; and (2) molding the mixture at a temperature sufficient to produce a self-supporting structure comprising the powder and gel.

  • Patent number: 5032555
    Abstract: Zirconia toughened alumina (ZTA) is produced from precursor salts. The precursor salts are coprecipitated from solution to yield a gel in a liquid phase. The gel in excess of the critical temperature and pressure is dried at a temperature and pressure in excess of the critical temperature and pressure of the liquid phase to thereby convert the liquid phase to a gas. The solid particles, when separated from the gas, form a fine particulate ZTA which, upon consolidation yields near theoretical density toughened ceramics.

  • Patent number: 4734237
    Abstract: A process for shaping parts from metallic and/or ceramic powders is disclosed. The process comprises the steps of forming a mixture comprising metal and/or ceramic powders, a gel-forming material having a gel strength, measured at a temperature between 0.degree. C. and about 22.degree. C. and a gel consisting essentially of about 4 wt. % of the gel-forming material and water, of at least about 100 g/cm.sup.2, and a gel-forming material solvent, and molding the mixture at a temperature sufficient to produce a self-supporting article comprising the powder and a gel. The preferred gel-forming material is an agaroid and the preferred molding process is injection molding.

  • Patent number: 4713233
    Abstract: Inorganic metal oxides having high surface area and pore volume are prepared by spray drying. The admixture which is spray dried to yield the metal oxides is produced from reactants comprising at least one hydrolyzable metal compound, a sufficient amount of water to at least partially hydrolyze the metal compound and an organic solvent. The admixture is supplied as a plurality of droplets to a reaction zone operated under conditions of temperature and pressure below the critical temperature and pressure of the reactants but sufficient to produce a product comprising metal oxide powders and a gas comprising organic solvent vapors. The powders are separated from the gas in a known fashion and collected. Spray drying of non-aqueous systems unexpectedly produces metal oxides having properties generally intermediate conventionally produced oxides and aerogels.

  • Patent number: 4675465
    Abstract: A process using hydrogen dissolving metals, alloys and intermetallic compounds to drive otherwise thermodynamically unfavorable dehydrogenation reactions is disclosed. The process comprises the steps of selecting an organic reactant comprising carbon and hydrogen, and exposing the organic reactant to a material at a temperature and pressure sufficient to remove at least one hydrogen from one said organic reactant and to form a material hydride, the material being selected from the group of metals, alloys and intermetallic compounds having a negative standard free energy of formation for a hydrided product MH.sub.y, where M is the material, H is hydrogen and y is a non-zero number between 0 and about 4 and represents the total hydrogen to material atom ratio wherein the standard free energy change for the reaction of the organic rectant in the present of the material to remove at least one hydrogen atom therefrom and from the material hydride is negative.
