| 摘要 |
A metal film electrode on the outer surface of an electroded, oxygen-ion-conducting solid electrolyte, closed end portion of an oxygen sensor tube is maintained in contact with the electrolyte and in its electrical conducting function by a compressible, porous, ceramic boot firmly press-fit onto and over the electroded end portion in slidable and frictional engagement with the outer film electrode (including any connector or reinforcing wire therein or thereon). Boot has open porosity of greater than 50 (or 80) volume percent and can consist essentially of zirconia, such as a sintered mass of zirconia fibers. |
