Abstract
A seal is proposed for a sensor element of a gas sensor, in particular for determining the oxygen content in exhaust gases of combustion engines. The seal has a sealing element, which is fixed in position in a longitudinal bore of a metallic housing. The sealing element contains a mixture of steatite and at least one low-melting-point glass. To manufacture the seal, a prefabricated sealing ring made of a mixture of steatite powder and powdered glass is used, which is pressed in the longitudinal bore, the sealing ring being subjected to a thermal treatment, in which the glass is melted.
