A gas sensor is for determining at least one physical quantity of a gas, e.g., an exhaust gas of an internal combustion engine, the gas sensor having a sensor element that is fixed in a housing of the gas sensor by a seal assembly. The seal assembly includes a sealing element, which has a ceramic and/or a metallic material. After the heat treatment, the sealing element has a maximum decrease in volume of 5 percent, or an increase in volume, based on the volume of the sealing element prior to the heat treatment.

Gas sensor

A gas sensor includes a sensor element for determining at least one physical quantity of a gas, e.g., for determining the concentration of a gas component in an exhaust gas of an internal combustion engine or the temperature of the exhaust gas. The sensor element is fixed in position by the sealing system in a housing of the gas sensor. The sealing system includes at least one sealing element, which includes a mixture of a ceramic material and a glass. The hemisphere temperature of the glass is above 750&deg; Celsius.
