Abstract (en)
[origin: FR2857355A1] New mixed electronic and O 2- anion conductive material of a crystalline perovskite structure in which the electric neutrality of the crystalline lattice is conserved. The material conforms to a compound of formula - A (a)>(1-x-u)A' (a-1)>xA'' (a'')>uB (b)>(1-s-y-v)B (b+1)>sB' (b+beta )>yB'' (b'')>vO 3-delta ; a, a-1, a'', b, b+1, b+beta and b'' : whole numbers representing valencies of A, A', A'', B, B' and B''; a, a'', b, b'', beta , x, y, s, u, v and delta : such that the electrical neutrality of the crystal lattice is conserved; a : greater than 0; a'', b and b'' : greater than 0; beta : -2 to 2; a + b : 6; s : greater than 0 less than x; x and u : are greater than 0 less than 0.5 ; (x + u) 0.5; y and v : 0 - 0.9; (y + v + s) : 0 - 0.9; [u(a''-a) + v(b'' - b)-x+s+beta y+2delta ] : 0; and delta : less than delta is less than delta maxwith; delta min[u(a - a'') + v(b - b''-beta y] / 2; and delta max[u(a - a'') + v(b - b'')-beta y + x] / 2; A : Sc, Y or a lanthanide, actinide or alkaline earth; A' (differs from A) : Sc, Y, a lanthanide, actinide or alkaline earth; A'' : Al, Ga or Tl; B : a transition metal, able to exist in several possible valencies; B' : a transition metal, Al, In , Ga, Ge, Sb, Bi, Sn or Pb; B'' : a transition metal , alkaline earth, Al, In, Ga, Ge, Sb, Bi, Sn or Pb(B, B' and B'' differ from each other); Independent claims are also included for the preparation of these compounds and their uses.
