Exhaust gas sonde in which the insulation layer separating the heater from the solid electrolytes is formed by sintering a material containing Al2O3 charged with a pore forming material

摘要

In order to prevent internal stresses and thereby cracking, the exhaust gas sonde is substantially ZrO₂And two measurement electrodes separated by a dielectric layer composed of Al₂O₃And a conductor strip layer for electrically heating the electrical layer that is strongly bonded to the dielectric layer by a first gas tight sintered insulating layer. Prior to sintering, the porosity-₂O₃/RTI
