Conductivity and stability of SrVO3 and mixed perovskites at low oxygen partial pressures

The electrical conductivity and chemical stability of ABO3 (where the A-site contains La or Sr, and the B-site contains Ni, V, Ti, Nb, Mo or W and combinations thereof) have been studied in air and reducing atmospheres. Neither the rare-earth vanadates, such as LaVO3, nor the alkaline-earth vanadates, with the exception of SrVO3, are good electronic conductors. SrVO3 shows excellent electronic conductivity of 1000 S/cm at 800°C and an oxygen …
