Abstract (en)
[origin: EP0926700A2] A vessel (4) has a main body (10) and a plugging member (11a) made of alumina. A composite electrode (6a) has a cylindrical current conductor having substantially the same diameter as the opening at one end of the vessel, and an electrode (14a) joined by welding at the end of the current conductor exposed to inside of the vessel. The current conductor of the composite electrode has a cylindrical member (13a) made of alumina and a metallization layer made of molybdenum and alumina. The vessel and the composite electrode have bene subjected to co-firing into an integrated body, with the composite electrode inserted into the opening portion at one end of the vessel so that the electrode is exposed to the inner space with one end of the composite electrode exposed outside of the vessel. <IMAGE>
