しくない。However, when a β-alumina tube is molded using a mandrel and a bottom punch having a surface layer as described above, the molding powder adheres to the surface of the β-alumina tube, and the molding powder is molded. There was a problem that the surface of the β-alumina tube was uneven. If the molding powder adheres to the surface of the mandrel and the β-alumina tube has an uneven inner surface, the sodium-sulfur battery deteriorates quickly. Also, if there is unevenness on the open end surface of the β-alumina tube due to the sticking of the molding powder to the upper surface of the bottom punch, baking is performed with the open end facing down, so deformation is likely to occur during baking and dimensional accuracy is maintained. It is not preferable for doing.

There is also a problem that the operation efficiency of the CIP molding apparatus cannot be improved. Further, there is a problem that a device for removing the powder is required and the production cost of the β-alumina tube cannot be reduced.

処理による蒸着に比べ、基体との密着性に優れている。The ion plating treatment is a type of PVD (Physical Vapor Deposition) treatment. Ions generated therein are directly deposited on the surface of the substrate. That is, by applying a negative high potential to the substrate in the vacuum container to generate glow discharge between the chromium nitride and the substrate, the inert gas is ionized and collides with the chromium nitride. By doing so, atoms are ejected from the chromium nitride and these atoms are also ionized. The ions are accelerated by the electric field generated by the negative charge applied to the substrate, and collide with the substrate with high energy to be deposited. Vapor deposition by ion plating is used for other PVD such as vacuum vapor deposition and sputter vapor deposition.
Excellent adhesion to the substrate compared to vapor deposition by treatment.

い。In the present invention, a portion of the surface of a metal member such as a mandrel or a bottom punch that comes into contact with the molding powder needs to have a layer made of chromium nitride, but a chromium nitride layer is formed on the entire surface. Is more preferable. The molding rubber mold and top rubber plug also come into contact with the molding powder during molding, but these are made of rubber, and unlike metal mandrels or bottom punches, there is no problem of powder sticking, so chromium nitride is used. There is no need to form layers.
