An oxygen sensor is composed of or contains a composite solid electrolyte material and, optionally, a body of a non-conducting ceramic material. The composite solid electrolyte material comprises a mixture of at least two constituents, one of which is a good oxygen ion conductor and the other a non-electrolyte ceramic. Magnesium aluminate spinel may be used for the non-conducting ceramic material in the composite solid electrolyte and for the body of the oxygen sensor. |
