Abstract
A lean-burn oxygen sensor composed of two different sintered semiconductors was made by electrically contacting the discs of SrAl0.01Ti0.99O3 and Cr2O3 with Pt mesh by mechanical pressing. The resistance-λ′ characteristic of the connected device was investigated in the exhaust gas of oxygen-propane combustion, where λ′ stands for the oxygen excess ratio. It was found that the SrAl0.01Ti0.99O3Cr2O3 device had promising properties for a lean-burn oxygen sensor, because the device exhibited a large change in the resistance in the lean-burn region with a negligible change in the rich-burn region.Keywords
