Abstract
A ceramic sensor is disclosed that includes a ceramic tube having a closed end and an open end, and a metal sleeve having open first and second ends. 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.
