<p>A sensor and a method for making a sensor is disclosed. The method for making the sensor comprises: mixing a first metal oxide stabilized alumina with alpha alumina in a liquid to create a base slurry, mixing into said base slurry a second metal oxide stabilized alumina and a fugitive material to create a composition; applying said composition to at least a portion of a sensing element comprising two electrodes with an electrolyte disposed therebetween; and calcining said sensing element. One embodiment of the sensor comprises: a sensing element comprising a first electrode and a second electrode having an electrolyte disposed therebetween, wherein a protective layer is disposed in physical contact with a side of said first electrode opposite said electrolyte; and a protective coating disposed over at least a portion of said protective layer on a side of said protective layer opposite said first electrode, said protective coating comprising a milled metal oxide stabilized alumina, an alpha-alumina, an un-milled metal oxide sttabilized alumina.</p> |
