Abstract
The present invention relates to new conductive perovskites containing oxygen and nitrogen, their preparation and their use particularly as electrode material. The conductive perovskites containing oxygen and nitrogen according to the invention correspond to the general formula I EQU AB(O,N).sub.3 (I) in the cationic lattice of which: PA0 A denotes a metal chosen from the metals of groups IA and IIA, yttrium and the lanthanides, PA0 B denotes a metal chosen from the transition metals of groups IVA to IB, on the express condition that at least one of the metals A and B is present in an oxidation state other than its normal maximum oxidation state.
