Abstract
Single phase (La,Sr)(Al,Mn)O3 perovskites were synthesized and their electrical conductivity was studied as a function of temperature and oxygen partial pressure. The electrical conductivity was found to increase with Mn content, temperature and oxygen partial pressure, thus (La, Sr)(Al, Mn)O3 may be regarded as a diluted system of (La,Sr)MnO3. The highest electrical conductivity at 810 °C in air and humidified Ar/4% H2 was observed for (La0.8Sr0.2)0.94Al0.5Mn0.5O3 and reached 12 and 2.7 S/cm, respectively.
