Influence of Pt paste and the firing temperature of screen-printed electrodes on the NO detection by pulsed polarization [PDF]
Journal of Sensors and Sensor Systems, 2020 Symmetrical Pt|YSZ|Pt sensors were produced by screen printing with frit-containing and fritless Pt pastes and fired at 950, 1100, and 1300 ∘C. Subsequently, the sensors were operated by pulsed polarization, and the NO sensitivity was investigated.
