Descripción
The crystal chemistry and mixed conductor properties of the n = 2 member of the Ruddlesden-Popper (R-P) phases Sr3-xLaxFe2-yNiyO7-δ with 0 ≤ x ≤ 0.3 and 0 ≤ y ≤ 1.0 have been studied at high temperature. High-temperature X-ray diffraction and thermogravimetric measurements of the equilibrium pO2 (10- 5 ≤ pO2 ≤ 1 atm) in the temperature range 400 ≤ T ≤ 1000 °C indicate that the Sr3FeNiO7-δ phase is able to accommodate a large oxygen non-stoichiometry (δ ∼ 1.5) without structural transformations. The electrical conductivity and oxygen permeability increase with the substitution of Ni for Fe in the range 550 ≤ T ≤ 1000 °C. The electrical transport of the Sr3FeNiO7-δ phase is thermally activated and the activation energy decreases with the substitution of Ni for Fe for a given oxygen content. The increase in the oxygen permeation flux with increasing Ni content is due to an increasing oxygen non-stoichiometry and a lower activation energy for permeation.
