Oxygen sensor based on undoped cuprate

摘要

Ln represents at least lanthanum or a trivalent element in the group of elements Nos. 58 to 71, and a stoichiometry y of O ₂ is a cue mixed with oxides of the general formula Ln ₂ CUO _{x + y} in the range of 0.001 to 0.1. Plates are particularly suitable for use in oxygen sensors, eg waste gas plants.
