Abstract The nitrogen-sensing properties of LaAl12O18N are described for the first time. Positive e.m.f. measurements at high temperature across the cells α-Nb (N), β-Nb2N, α-Al2O3, LaAl12O18N∣LaAl11O18 (or LaAl12O18N)∣LaAl12O18N, α-Al2O3, β-Nb2N, γ-Nb4N3, were in agreement with PN2(β-Nb2N, γ-Nb4N3)〉PN2(α-Nb(N), β-Nb2N) for the idealized stoichiometric cell reaction γ-Nb4N3+2α-Nb(N)→3β-Nb2N, thus demonstrating the nitrogen-sensing property of these cells. The e.m.f. for a variety of cells with electrodes containing β-V2N, β-Nb2N, β-Ta2N and “Ti2N”, were consistent with the predicted equilibrium nitrogen partial pressures.
