    摘要： An extrusion mold for molding a ceramic membrane having an one-end closed tube structure which is easily integrated and has a high gas separation efficiency, and a fabrication method of a ceramic membrane tube using the same, the extrusion mold comprised of an outer mold, an inner mold and an extrusion hole end cap, wherein the cap has a through hole at its center for controlling an extrusion molding density, and a passage is formed in each of the inner and outer molds for maintaining an inner pressure of an extruded tube to be the same as an outer pressure. The one-end closed ceramic membrane tube is fabricated by supplying a ceramic mixture into the extrusion mold in a state that the end of the extrusion hole of the extrusion mold is closed by the cap, removing the cap after filling the mixture in the end of the extrusion hole, and further supplying the mixture into the extrusion mold to obtain a tubular ceramic extrusion body with a particular length.

    摘要： A method for producing a sleeve having a closed end by extruding a forming material from a mouthpiece. A core member is arranged in position in the mouthpiece and has a piston member detachably provided in a tip end of the core member. The piston member has an air communication aperture. On the other hand, an outer die is arranged in the mouthpiece for forming an outer configuration of the closed end. As a result, an annular space is formed by the mouthpiece, core member and outer die. The forming material is then supplied into the annular space and extruded to form the closed end of the sleeve. After the outer die has been removed from the mouthpiece, the piston member is caused to slide relative to the mouthpiece and at the same time the air is blown into an inside of the closed end through the air communication aperture of the piston, while the forming material is further supplied and extruded from the mouthpiece to form the closed end sleeve.

    摘要： A process for the preparation of ceramic articles having a thickness of at least about 2.5 cm, which comprises:a) selecting the ceramic composition from the group consisting of silicate material, metal oxides, nitrides and carbides, and mixtures thereof, optionally adding ceramic fibers, such as boron nitride or silicon carbide fibers, to the ceramic composition,b) autoclaving the ceramic composition to increase its hydrogen form contents, which increases the composition's microwave absorptivity,c) forming the ceramic composition into the desired shape, andd) subjecting the composition so shaped to microwave energy to internally heat and thereby dry and sinter the composition, optionally with external heat applied by means of electrical resistance or gas fired heating. Novel apparatuses for the extrusion and vibrocompaction of ceramic compositions, the drying of ceramic masses, kilns for microwave-assisted firing of the ceramic articles, cars, and a hydraulic air handling system for tunnel kilns.

    摘要： A process for forming an end cap in an extruded ceramic tube. An end cap forming cavity of an end cap forming die is positioned so that, when the body of the end cap forming die is situated against an extrusion die, ceramic material is able to be forced into the end cap forming cavity, through a passageway communicating between the end cap forming cavity and a backfill reservoir, and into the backfill reservoir. A plunger projects into the backfill reservoir to force the ceramic material from the backfill reservoir back through the passageway and into the end cap forming cavity to compact the ceramic material so that the ceramic material within the end cap will be provided with a substantially uniform density.

    摘要： A method of manufacturing porous ceramic tubes for fuel cells with improved properties and higher manufacturing yield is disclosed. The method involves extruding a closed end fuel cell tube, such as an air electrode of a solid oxide fuel cell, in which the closed end also functions as the sintering support. The resultant fuel cell tube has a superior porosity distribution which allows improved diffusion of oxygen at the closed end of the tube during operation of the fuel cell. Because this region has the highest current density, performance enhancement and improved reliability of the fuel cell tube result. Furthermore, the higher manufacturing yield associated with the present method decreases the overall fuel cell cost.
