PURPOSE:To make the sintering of a thin beta alumina tube having small dimensional tolerance possible without the hanging breakage of the molding by forming the outside of the opening end of the beta alumina tube molding in a taper and inserting it into a supporting plate having a tunnel shaped receiver whose taper corresponds to the taper of the beta alumina tube molding for hanging. CONSTITUTION:The outside of the opening end of a beta alumina tube molding 10 is formed in a taper, and it is inserted from the upper side in a upper side opened container with a supporting plate 12 having a funnel-shaped receiver whose taper corresponds to the taper of the beta alumina tube molding 10 for hanging. The container 11 is covered with a cover 15 made of the same material as the container 11, the sintering is conducted. The weight of the beta alumina tube molding 10 is received as surface load. The hanging breakage of the beta alumina tube molding is avoided and a thin beta alumina tube having small dimensional tolerance can be sintered. |
