The ceramic tube is formed of stabilized zirconia. The metal sleeve extends about the open end of the ceramic tube and is sealingly joined thereto at a contact region by a brazeless bond resulting from hot isostatic pressing. A mixture of metal and metal oxide powders is provided within the ceramic tube adjacent the closed end, and a conducting wire extends from the mixture of metal and metal oxide powders to the second end of the metal sleeve.
