摘要
The present invention relates to new nitrogen or oxynitrogen compounds of perovskite structure, corresponding to the general formula I: ABO3-nNn (I) in which: the cationic lattice consists of: a metal cation A chosen from the group comprising: Li+, Na+, K+, Rb+, Cs+, Ag+, Tl+, Ca2+, Ba2+, Sr2+, Pb2+, Cd2+, Ln3+, Bi3+, Y3+, Th4+, U4+, trans-U4+; and a metal cation B chosen from the group comprising: W6+, Re6+, Mo6+, Ta5+, Nb5+, Mo5+, W5+, Ti4+, Zr4+, Sn4+, Ge4+, Nb4+, Ta4+, Al3+, Ga3+, In3+, Tl3+, Fe3+, Cr3+; n=1, 2, or 3, and the cationic charges a of the metal A and b of the metal B satisfy the equations: a+b=6+n a/=n, and the solid solutions of these compounds.
