摘要： Methods have been developed to make porous ceramic membranes having macroscopic channels therethrough. The novel membranes are formed by temporarily supporting the sol-gel membrane precursor on an organic support which is ultimately removed from the interior of the membrane, preferably by pyrolysis or by chemical destruction. The organic support may also include an inorganic metal portion that remains on destruction of the organic portion, providing structural support and/or chemical reactivity to the membrane. The channels formed when the organic support is destroyed provide the ability to withdraw small catalytic products or size-separated molecules from the metal oxide membrane. In addition, the channel-containing membranes retain all of the advantages of existing porous ceramic membranes.

摘要： Ceramic bodies suitable for use in the filtration of molten metal are formed by immersing a porous organic substrate material in an aqueous thixotropic slurry containing yttria, zirconia and alumina; expelling excess slurry; drying the impregnated material; and heating to an elevated temperature to burn off the organic material and sinter the ceramic materials. The resulting zirconia-alumina ceramic bodies have from about 5-80% of the zirconia in a monoclinic phase and the remainder of the zirconia essentially in a stabilized cubic phase due to the yttria. The ceramic bodies thus produced have excellent strength, density, and thermal shock resistance properties.

摘要： Electrically semi-conducting and conducting open celled ceramic networks and methods for producing them are disclosed. The ceramic network is formed by impregnating an organic foam material with a semi-conducting or conducting ceramic composition, and firing the impregnated material to burn out the foam and to vitrify the ceramic. The semi-conducting or conducting ceramic composition may comprise, on a solids basis, from 45 to 80 percent of a lead-free ceramic frit, from 5 to 15 percent of mono aluminum phosphate, from 6 to 45 percent of a silicone resin, from 0.2 to 13.2 percent of a conducting carbon compound, and an organic solvent or water in an amount sufficient to form a dispersion having a viscosity ranging from 300 to 3000 centipoises, and, in the latter case, from 0.5 to 7 percent of a detergent. The electrically semi-conducting or conducting ceramic composition may also comprise, on a solids basis, a modified copper and alumina composition, from 6 to 45 percent of a silicone resin, and an organic solvent or water and detergent to produce a dispersion having a viscosity ranging from 300 to 3000 centipoises. The organic solvent systems and the aqueous systems both constitute dispersions.
