Gas sensor used for selective detection of nitrogen dioxide in gaseous mixture, has strip conductor that is arranged between platform and sensing electrode which is comprised of titanium-aluminum mixed oxide rich in titanium

摘要

The gas sensor has a platform (1), a sensing electrode (3), and a strip conductor (2) that is arranged between the platform and the sensing electrode. The sensing electrode is comprised of titanium-aluminum mixed oxide that is rich in titanium. The platform is comprised of aluminum oxide and zirconium oxide. The strip conductor is comprised of precious metal particularly platinum. The content of aluminum in titanium-rich titanium-aluminum mixed oxide region is from 0.2-6 atom%. An independent claim is included for a method for manufacturing gas sensor.
