The invention relates to a method for the production of a shaped body comprising at least the method steps of producing a blank having an open porosity by pressing and treating pourable material in a first heat treatment step comprising or consisting of a metal oxide, infiltrating the blank with an infiltration fluid containing a precursor of the metal oxide, precipitating hydroxide of the metal from the infiltration fluid by treating the blank with a basic solution, forming the metal oxide from the hydroxide by treating the blank in a second heat treatment step, wherein the blank is processed before or after the second heat treatment step to achieve a shape that corresponds to the shaped body.

The present invention relates to sintered balls comprising tungsten carbide (WC) and partially stabilized zirconium oxide, nX:ZrO.sub.2,, and to powder mixtures and green bodies for the production thereof, and to methods for the production of the green bodies and the sintered balls. The sintered balls have high densities, high wear resistance and a long service life.

A tool to differentially compress a powder material comprises a differential compression piston and a support. The piston comprises a first part configured to apply a pressure on a first region of an external surface of the powder material. The piston comprises a second part with a recess which is located at a lateral distance from the first part and which is configured to face a second region of the external surface of the powder material. The tool further comprises a membrane that can be deformed by the piston. The deformable membrane is configured to at least partially retain the powder material in the tool.

A method for forming a friction facing comprises placing a bonding powder mix in to a die, and placing a performance powder mix in to the die. Pressing the performance powder mix and the bonding powder mix creates a compact. Sintering the compact forms a friction facing. A clutch disc assembly can be formed. A clutch disc can comprise a mounting hole for securing a friction facing and a backer plate can comprise a pass-through hole. A mounting mechanism joins the mounting hole to the pass-through hole. The mounting mechanism comprises a head-height for a portion of the mounting mechanism that is mounted near the sintered compact. The bonding layer comprises a thickness corresponding to the head-height of the mounting mechanism.

A sputtering target having a composition of LiCoO.sub.2, wherein a resistivity of the target is 100 cm or less, and a relative density is 80% or higher. The sputtering target of the present invention is effective for use in forming a positive electrode thin film in all-solid-state thin-film lithium ion secondary batteries equipped in vehicles, information and communication electronics, household appliances, and the like.

A ceramic body prosthetic implant or prosthetic implant component of a magnesium oxide stabilized transformation toughened zirconia (Mg-TTZ) ceramic can be made by providing a bisqued initial green body of ceramic by providing a powdered ceramic material, which substantially is a monoclinic zirconia having magnesium oxide for a stabilizer, and, without employing a binder additional to the powdered ceramic to do so, compressing the material in its powder form through a cold isostatic press operation to form a raw, pressed initial green body, and then heating the raw, pressed initial green body to a bisque stage to provide the bisqued initial green body. Then, the following further steps are carried out: without embedding the bisqued initial green body of ceramic in an embedding mass, machining the bisqued initial green body to provide a machined, bisqued green ceramic body such that the machined, bisqued green ceramic body has a shape, which is a precursor shape essentially analogous to, being of the same proportions as, the shape of, but larger than, the ceramic portion of a fired predetermined finished ceramic body prosthetic implant or prosthetic implant component; and then firing the machined, bisqued green ceramic body to provide a fired Mg-TTZ ceramic body product, which is the same size and shape or essentially the same size and shape as the ceramic portion of the fired predetermined finished ceramic body prosthetic implant or prosthetic implant component.

The present invention relates to a continuous manufacturing method for a vacuum insulation material, including: a first step of putting a porous insulation material into an inner envelope having permeability, three sides thereof being closed and one side thereof being open, and then sealing the inner envelope; a second step of flattening an upper broad side of the inner envelope; a third step of compressing the inner envelope flattened in the second step; a fourth step of sealing all sides of the inner envelope compressed in the third step, except for one side, with an outer envelope having a shielding property, and packaging the sealed inner envelope; and a fifth step of sealing the one side of the inner envelope not sealed in the third step by putting the inner envelope sealed in the fourth step into a vacuum chamber and performing a vacuum operation.

A concrete product is produced by providing red dune sand having a particle size of 45 microns or less and mixing the red dune sand with hydraulic cement in a ratio of about 30% of the cement being replaced by the red dune sand. The cement and red dune sand are then mixed with fine and course aggregate, water and a superplasticizer and cast after pouring into a mold cavity. Then within 24 hours of casting, the cast article is steam cured for 12 hours under atmospheric pressure, demolded and placed in an auto clave at 100% humidity. The temperature in the auto clave is raised to 180 C. within one to two hours and maintained at that temperature for 4 to 5 hours. The temperature also increases the pressure to about 10 bars. The pressure is released to reach atmospheric pressure within 20-30 minutes and the temperature reduced gradually, so that the article can be removed.

A system and a method for molding a part from fiber cement, or fibrocement, slurry are provided. The molding is preferably made by pressure injection of the slurry. The slurry includes cementitious material, additives, fibers and water. The fibers can include polypropylene, polyethylene, polyacrylic, cellulose, and/or asbestos fibers. First and second molding sections define, at least partially, a chamber. The second molding section has at least one evacuating channel. The system includes a slurry inlet communicating with the chamber, for inserting the slurry. A bladder covers the first molding section, the bladder being inflatable for compressing the slurry between the bladder and the second molding section. A filter covers the second molding section and allows water contained in the slurry to pass through while retaining the cementitious material and fibers within the chamber. A pressurized fluid inlet port communicates with at least one conduit for inflating the bladder.

The present invention provides a method of forming a frame core (1) having a center leg (3) for an inductive component, and an accordingly formed frame core (1) having a center leg (3) and an air gap (4) in the center leg (3). The frame core (1) is formed integrally with the center leg (3), the air gap (4) being molded into the center leg (3) during the formation of the frame core (1).
