Description
<p>A potentiometric solid-state sensor using a Na5DySi4O12 solid-electrolyte and oxide electrodes was tried to examine for monitoring HCl gas. Among the oxides tested, the sensor using RuO2 electrode showed relatively good HCl response at 400°C. The electromotive force was almost linear to the logarithm of HCl concentration between 100 and 1000 ppm. This HCl sensor showed also good selectivity to CO2, NO, and NO2, and few effect of oxygen. A mixed potential sensing mechanism is tentatively proposed.</p>
