Sr and Baβ-aluminas in a single phase were synthesized in the MO-MgO-Al2O3 (M = Sr and Ba) system by a solid state sintering method. The electrical conductivity was measured at 873 to 1473 K by an AC impedance method. The total electrical conductivities of Srβ-alumina and Baβ-alumina were 1.2×10-2 S m-1 and 6.7×10-4 S m-1 at 1473 K, respectively. A CO2 gas sensor using the Srβ-alumina was constructed. The sensor could be used at more than 1000 K.
