A semiconductor-type sensor applicable to the monitoring of N2O in air was studied. As revealed by a screening test, n-type oxides such as SnO2, In2O3, WO3, and ZnO were more or less sensitive to N2O, while the highest sensitivity was obtained with SnO2. However, the N2O sensitivity of SnO2 was not sufficient for practical application. The addition of SrO to SnO2 was effective for improving N2O sensitivity. Thus 0.5 wt % SrO-SnO2 was about three times as sensitive as pure SnO2, allowing good detection of 10-300 ppm N2O in air at 500 °C.
