| Abstract: | Solid electrolyte cells for detecting NO2 with Ba(NO3)2 or Sr(NO3)2 partially replaced by  -Al2O3 as solid electrolytes have been studied. The cell tension depends on the NO2- as well as on the NO-concentration. Investigations of the establishment of the NO2-NO-O2-equilibrium by the catalytic effects of the used electrode materials Pt and Au have shown that a decomposition of NO2 below 400°C cannot be expected.17th Communication on oxoanionic solid electrolytes and their possible applications; 16th Communication see Solid State Ionics 51:183–185 (1992)Extension of a part of the lecture of V.
