The oxygen permeability and stability of dense Pr 2 NiO 4+δ ceramics have been appraised in comparison with K 2 NiF 4 -type lanthanum nickelate. In oxidizing atmospheres, Pr 2 NiO 4+δ exhibit an extensive oxygen uptake and decomposition into the Ruddlesden-Popper-type Pr 4 Ni 3 O 10 and praseodymium
