We have studied the stability of Pr 2 NiO 4؉ under pure oxygen 6ow by in situ measurement of its weight versus T. Above 8503C a fast oxidation is observed corresponding to the ex-solution of PrO y species and to the formation of metallic Pr 4 Ni 3 O 10؊x . This reaction is not reversible. The quanti
