A method for the manufacture of a seal for a sensor element of a sensor for detecting at least one property of a measurement gas in a measurement gas space

摘要

It is a method for the manufacture of a seal (42, 46) for a sensor element (30) of a sensor (10) for detecting at least one property of a measurement gas in a measurement gas space, in particular for the detection of a portion of a gas component in the measuring gas or a temperature of the measurement gas, is proposed. The method comprises the steps of:– Providing a ceramic material, the at least boron nitride and boron trioxide, wherein a portion of the boron trifluoride oxide based on the ceramic material either from 2,0 w -% to 6,0 w -% or more than 6,0 w -% and not more than 10,0 w -% is.– shaping pressing of the ceramic material to a seal (42, 46) and– To increase the strength of the sealing body by temperature treatment (42, 46).
