Title:
GAS SENSOR
Document Type and Number:
Japanese Patent JP2001091493
Kind Code:
A
Abstract:

To provide a gas sensor preventing an electrode material on a zirconia solid electrolyte substrate from evaporating and warping and having high sensor electrode performance and reliability.

In an electrochemical sensor constituted of a detection electrode 3 at least being active to a detected gas and a counter electrode, or a reference electrode 4 paired with the detection electrode in a zirconia sold electrolyte having oxygen ionic conductivity, Al as an additive element is dispersed and solutioned in the zirconia solid electrolyte by 0.001-1.0 wt.%.
